Achieving high near-room-temperature thermoelectric performance through compositionally tuned hybridization of n-type Ag0:Ag2Se

 

Thermoelectric materials enable the direct conversion of thermal to electric energy, and as such, have received considerable attention as a source of sustainable clean energy. The performance of a thermoelectric material is characterized by the dimensionless figure of merit, zT = S2σT/κ, where S is the Seebeck coefficient, σ is the electrical conductivity, κ is the thermal conductivity, and T is the absolute temperature. Achieving high zT requires careful design of low thermal conductivity and high power factor (PF = S2σ). Typically, thermoelectric materials with a high zT are heavily doped semiconductors, which have been extensively studied at medium and high temperatures, but less so at near room temperature. Recently, orthorhombic Ag2Se has attracted much interest for near-room-temperature thermoelectric applications as they are anticipated to catalyze tremendous growth in energy harvesting for advancing internet of things appliances, self-powered wearable medical systems, and self-powered wearable intelligent devices. In order to optimize the thermoelectric performance of orthorhombic Ag2Se, it is vital to understand the correlation between composition, structure, and transport properties. A variety of methods have been successfully developed for the preparation of Ag2Se thermoelectric materials, including high-temperature solid-state reactions, room-temperature grinding, high‐energy mechanical milling, and pulsed hybrid reactive magnetron sputtering techniques. In comparison, solution‐based approaches are relatively less investigated for the synthesis of Ag2Se, though widely used for generating CdSe, ZnSe and Cu2-xSe compounds, as these methods offer the unique advantage of excellent control over material stoichiometry with high production throughputs at ambient conditions.

Recently, researchers at the Institute of Materials Research and Engineering (IMRE), Agency for Science, Technology and Research (A*STAR), and Tianjin University, demonstrated a high ZT value of near unity at near-room-temperature through compositionally tuned hybridization of n-type Ag0:Ag2Se (Fig. 1). A series of n-type Ag0:Ag2Se materials has been systematically prepared through a surfactant-free, aqueous solution-based approach under ambient conditions. This strategy enables fine control over phases and compositions through nanoscale hybridization, yet remains applicable to large-scale production methods. By prolonging reaction times, the synthetic process is carefully developed/optimized to adjust the stoichiometry of Ag and Se by modulating the oxidation states of Ag and Se in the reaction medium, producing a series of Ag0:Ag2Se (Ag0 excess at 50.86%, 45.80%, 15.97%, 6.10%, 4.31% and 1.96%) with enhanced thermoelectric properties.

Fig. 1 Schematic synthesis of Ag0:Ag2Se hybrids for a period of 7 days at room temperature under aqueous condition, with different molar ratios of Ag:Se.

After hot-processing the powder by spark plasma sintering, the temperature-dependent electrical conductivity of 45.80% Ag0:Ag2Se prepared by reaction for 1 day was significantly higher than the rest of the Ag0:Ag2Se samples, which relates to its augmented carrier concentration due to hybridization with more Ag0. When the reaction time was prolonged, more Ag2Se was converted from Ag0, resulting in a drastic decrease in electrical conductivity for all the Ag0:Ag2Se samples including 6.10%, 4.31%, and 1.96% Ag0 from 3, 5 and 7 days of reaction, respectively. The temperature-dependent trends in Seebeck coefficient of Ag0:Ag2Se are opposite to those of electrical conductivity. These attributes lead to the lowest power factor for 45.80% Ag0:Ag2Se, in comparison to the rest of the Ag0:Ag2Se samples (Fig. 2a). In conjunction with fine-grained structure, which effectively scattered phonons at grain boundaries, the optimal excessive Ag0 of 1.96% after 7 days of reaction exhibited a high ZT value of close to unity (Fig.  2b).

Fig. 2 (a) Temperature dependence of power factors of the hot- pressed pellets of 45.80%, 6.10%, 4.31%, and 1.96% Ag0:Ag2Se, synthesized after reactions for 1, 3, 5, and 7 days. (b) Temperature dependence of ZT value of the 1.96% Ag0:Ag2Se pellet in comparison with the 4.31% Ag0:Ag2Se pellet.

Instead of doping or alloying, our work presents an effective way to organize different nanoscale building blocks by precise hybridization at nanoscale, preserving the intrinsic properties of Ag2Se without incorporating different elements. On this basis, it would be of great interest in extending this solution strategy to the synthesis of hybridized multinary silver-based chalcogenides for further enhancing thermoelectric properties. Additionally, this solution approach could also find uses in the general synthesis of other metal chalcogenides, particularly useful for large-scale production.

Recent developments in transition metal-based MOFs for electrocatalytic water splitting emphasizing fundamental and structural aspects

To combat global warming and the climate issue, clean and sustainable energy alternatives to fossil fuels must be developed. Due to the high energy density (142 kJ/mol) and lack of environmental effects, hydrogen is regarded as a clean fuel. Besides this optimistic view, there is still an urgent need for a green, sustainable, and efficient technique for mass production of hydrogen. Electrochemical water splitting is the only method to produce enormous quantities of highly pure hydrogen under favourable conditions, with only a by-product of water. The two half-reactions involved in electrochemical water splitting are the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER). The nominal breakdown voltage for splitting water is 1.23 V in theory, but in real electrolytic experiment, an extra energy (overpotential) is required to overcome the kinetic barrier and produce hydrogen at a fast enough rate. Overpotential causes energy consumption to rise, which reduces electrochemical water splitting efficiency and a system’s capacity to compete economically. So, the use of electrocatalyst would increase the current density at a given voltage by minimizing the overpotential and further catalysing the electrochemical processes. Hence, a powerful electrocatalyst with high catalytic performance and good static stability is essential for the commercially sustainable production of hydrogen on a wide scale using an electrochemical process. Apart from noble metals, an earth-abundant non-noble metal-based electrocatalyst has been developed significantly over the past few years to minimize the practical cost of the electrocatalyst.

Recently, researchers at the Materials Chemistry Laboratory for Energy, Environment and Catalysis at CSIR-Central Electrochemical Research Institute (CECRI), India has constructed a review on Metal-Organic Framework (MOFs) based materials as electrocatalyst for water splitting especially focusing on OER with brief description over the fundamental and structural aspects (Fig. 1). MOF will be used as a viable contender for many applications, including catalysis, sensing, luminescence, drug administration and imaging, adsorption and separation, gas and energy storage, due to the cage-like structure. The primary benefits of these MOFs include flexible and tunable chemical functions with a variety of organic linkers, tunable shape, high specific surface area, and configurable pore size. Again in this review, they briefly deliberated the most recent advancements in MOF-based electrocatalyst in terms of design and fabrication, characterisation, and catalytic mechanism towards water splitting reaction. In addition, this review also emphasized the challenges and potential of employing a MOF-based materials for water splitting.

  https://doi.org/10.1039/D2QM01264B  
     

My research interests

Key words: dye chemistry, photochemistry, computational chemistry, fluorophores, fluorescent probes
We conduct both computational and experimental studies on fluorescent dyes and sensors. We use both “bottom-up” and “top-down” approaches to systematically summarize molecular design rules. In the “bottom-up” approach, we employ quantum chemical calculations and experimental characterizations to understand the molecular origins of a particular dye, before generalizing such knowledge to a wide range of compounds. In the “top-down” approach, we perform “data mining” in chemical databases and search patterns between molecular structures and their properties; subsequently, we validate these patterns using quantum chemical calculations, and thereby generate molecular design rules.

These rational molecular design rules enable us to develop novel fluorescent dyes and sensors with enhanced performance. A deep understanding of the structure–property relationships of fluorophores also permits us to reveal the photophysics and photochemistry of various fluorescent compounds.

Our research vision is to shift the chemistry of fluorophores from “trial-and-error” to molecular engineering, such that one gains the ultimate abilities to “design” tailored fluorescent properties to suit a given application.

10 Facts about me

An accomplishment I’m particularly proud of is the discovery of a new charge transfer mechanism (twisted intramolecular charge shuttle).  

I am most passionate about my work in understanding the working mechanism of fluorescent compounds because it is fascinating to play with light at the molecular scale.

I published my first academic article on the invisibility cloak in 2010, as a research engineer. It teaches me the importance of teamwork. I have since switched my research directions several times, for curiosity and fun!

My biggest motivation to do research is to uncover the secrets of the natural world.

I advise my students to be critical about any views in the pursuit of science, including those from me.

If I were not a scientist, I would be a teacher. I enjoy teaching and interacting with students.

My passion besides work is reading and travel.

My favorite time of day is early morning at home, with the sunrise and music.

One thing I cannot live without is my family.

The most important thing I learned from my parents is caring for others.

My research interests

Key words: scanning probe microscope, Raman spectroscopy, tip-enhanced Raman spectroscopy, nanoscience, nanomaterials
The goals of my research group are to develop and apply scanning probe-based nanotechnology, including scanning tunneling microscopy (STM) and tip-enhanced Raman spectroscopy (TERS) to provide angstrom-scale mechanistic insights for complex chemical systems. My research is at the interface of Chemistry and Materials Science and provides the needed information about environmental heterogeneity in complex chemical systems such as nanostructures on metal surfaces and the surfaces of two-dimensional (2D) materials. My group is uniquely positioned to characterize these systems both spatially and chemically using STM and TERS. With the optical set-up which I designed, my group is now able to: (1) observe weak vibrational modes that would be lost with less sensitive Raman techniques, (2) improve the signal-to-noise ratio for TERS to investigate subtle changes in molecular binding at the atomic level, and (3) achieve spatial resolution of TERS below 1 nm. These findings will guide the rational design of nanoscale systems.

10 Facts about me

I published my first academic article as an undergraduate research assistant at the University of Science and Technology of China.  

An accomplishment I’m particularly proud of is developing a hybrid technique by combining scanning probe microscopy with optical spectroscopy to understand and predict the single-molecule processes at the angstrom scale.

I am most passionate about my work in pushing the spatial limit of chemical imaging because single-bond chemistry can be ultimately observed.

I have the highest respect for Prof. Richard P. Van Duyne. He was a role model and leader who asked hard questions and provided enthusiastic suggestions for paths forward while also appreciating each student or postdoc for who they were. Although Prof. Van Duyne passed away in 2019, his legacy lives on in the minds he molded where his passion for science lives on.

My favourite thing to do outside of work is traveling. I can explore the unknown world and learn more.

I chose chemistry as a career because chemistry can create new things.

A key experience in my education was having done multiple-major studies in multiple countries.

The biggest challenge for me is to convince others to believe in my crazy scientific proposals.

One thing that can make me happy for sure is visiting a new country (maybe a new planet in the future).

I advise my students to be valuable men, which is more important than just being successful men.

I published my first academic article in J. Mater. Chem. C in 2015, which is about the design of blue AIE luminogens and their application in OLEDs.

The goal of my research is to develop new materials that can be used in daily life.

I am most passionate about my work in organic room temperature phosphorescence because this in itself is an anomaly which easily arouses my curiosity.

In my spare time, I enjoy reading martial arts fiction.

My favourite thing is watching my little girl grow up happily.

I would like to share with my students: success comes from constant effort.

My most important role model is my advisor Prof. Zhen Li. His passion for scientific research has always impressed me and I learned a lot from him.

I always feel lucky to be able to do what I like with lovely people.
