Manganese as a Superior Dopant for Oxide Nanosheets in Water Oxidation

The efficiency of water splitting is severely limited by the oxygen evolution reaction (OER), due to sluggish kinetics and a substantial overpotential. To overcome this challenge, precious-metal based catalysts, such as IrO2 and RuO2, have been investigated and confirmed to exhibit good OER performance. However, the scarcity and high cost of these materials restrict their large-scale application.

 

Recently, the group of Derek Ho and collaborators of the City University of Hong Kong have demonstrated a one-step method for the synthesis of Mn doped ultrathin nickel-iron oxide (Mn-Ni-Fe-O) nanosheets, which simultaneously achieves an abundance of oxygen vacancies and high valance Ni3+ catalytic sites (Fig. 1). The Mn dopant exists in the form of mixed-valence Mn cations, which contributes to tailoring the electronic structure of the Ni and Fe sites, leading to outstanding OER catalytic performance.

Figure 1. Schematic of the preparation procedure of Mn-Ni-Fe-O nanosheets.

 

 

SEM and TEM images of the Mn-Ni-Fe-O hybrid shows 100 – 300 nm interconnected nanosheet structures, having an ultrathin and veil-like morphology (Fig. 2). AFM images show a nanosheet thickness of approximately 3.2 nm. EDX mapping presents that Ni, Fe, Mn, and O elements are uniformly dispersed throughout the nanosheets.

 

Figure 2. (a) SEM image, (b, c) TEM images and the inset in (c) is the corresponding SAED patterns, (d) HRTEM image, (e) AFM image and the corresponding thickness curve, (f) STEM image and the corresponding element mapping, and (g) EDX spectrum of the Mn-Ni-Fe-O nanosheets.

 

 

XRD, XPS, CV, and EPR are also performed (Fig. 3). From XPS, after Mn doping, the Fe 2p3/2 XPS peak of the Mn-Ni-Fe-O nanosheets shifts to a higher binding energy as compared to that of undoped Ni-Fe-O nanosheets, suggesting that Mn dopant can modulate the charge density of Fe atom sites. Compared to the Ni 2p XPS spectrum of pristine Ni-Fe-O, the Ni 2p XPS spectrum of Mn-Ni-Fe-O nanosheets exhibits an obvious positive shift of 0.3 eV in binding energy, which is attributed to Mn incorporation. From CV curves, the Ni2+ oxidation peaks appear at 1.40 and 1.36 V versus RHE for the undoped and doped samples, respectively, indicating the oxidation of Ni species is enhanced upon Mn doping. Also, the O2 ratio (51.0 %) for the Mn-Ni-Fe-O nanosheets is higher than that of the Ni-Fe-O nanosheets (41.9 %), which indicates that Mn dopants can create an enhanced oxygen vacancies concentration.

Figure 3. Characterization data of the Mn-Ni-Fe-O and Ni-Fe-O: (a) XRD patterns, (b) XPS survey spectra, (c) high-resolution XPS spectra for Mn 2p region for Mn-Ni-Fe-O, (d) XPS for the Fe 2p region, (e) XPS for the Ni 2p region, CV curves (scan rate of 50 mV s-1) of (f) Ni-Fe-O  and (g) Mn-Ni-Fe-O, (h) XPS for the O 1s region, and (i) electron paramagnetic resonance (EPR) spectra of Mn-Ni-Fe-O (2 wt%).

 

 

OER electrochemical performance has been investigated in an O2-saturated KOH (1 M) solution. Upon doping of Mn, polarization curves show an OER overpotential of only 225 mV (vs. undoped at 250 mV) (Fig. 4). Remarkably, these two as-prepared ultrathin nanosheets, with or without Mn doping, exhibit faster OER than the commercial RuO2. The Mn doped nanosheets exhibit a turnover frequency (TOF) of 0.063 s−1 at the overpotential of 300 mV, which is 3.5 and 12 times higher than that of the undoped sample and commercial RuO2, respectively. The Tafel slope is 38.2 mV dec-1 (vs. 65.8 mV dec-1 undoped and 72.0 mV dec-1 from RuO2). Electrochemical impedance spectroscopy (EIS) reveals that the Mn dopants can effectively improve the electrical conductivity.

Figure 4. (a) Polarization curves, (b) TOF, and (c) Tafel slope of Mn-Ni-Fe-O, Ni-Fe-O, and RuO2. (d) Nyquist slopes of Ni-Fe-O and Mn-Ni-Fe-O, (e) overpotential at 10 mA cm-2 and Tafel slope of Ni-Fe-O nanosheets with different Mn doping levels, and (f) chronopotentiometry curves of Mn-Ni-Fe-O nanosheets at 30 mA cm-2.

 

 

This work demonstrated a facile method in synthesizing ultrathin Mn-Ni-Fe-O nanosheets that achieve highly efficient OER catalytic performance, providing a sound strategy for the design and synthesis of multi-metallic, atomically-thin oxides nanosheets to mitigate the catalytic limitation of OER, thereby rendering the electrolysis of water a practical form of alternative fuel production.

Topics and Questions:

  • We often receive the message that it’s in our career interests to not “rock the boat” and speak out against the norms or status quo of our community. Do you agree with this, and to what extent?
  • Please share some examples in which you have used your voice to speak out against something that you disagreed with. Could be challenging a scientific concept or shutting down discrimination, etc.
  • Was there ever a time when “being bold” backfired for you? What did you learn from the situation?
  • How have you navigated pivots or new directions in your career?
  • How have you remained bold in the face of rejection?

Attendees:

Students and postdocs of Northwestern University

In the panel, the scientists addressed questions and shared how they had learned to be bold scientists, educators, and working professionals. Some suggested for students were, finding out what they were good at and building on that, being bold to talk to their professors, talking to the top players in the field when there was a chance and reaching out to more people. They also shared their own stories about being bold and confident. This Panel offered a great opportunity for students to interact with scientists and seek for advice on future development.
