How do you feel about Reaction Chemistry & Engineering as a place to publish?
Reaction Chemistry & Engineering is an excellent place to publish high quality articles for newly design functional nanomaterials and their efficient utilization at the reactor scale for diverse applications in environmental remediation e.g., clean water, pollution abatement and beyond. I am honoured to share my research work.
What aspect of your work are you most excited about at the moment and what do you find most challenging about your research?
My work focuses on maximizing charge carrier collection via interfacial tuning of the photocatalyst heterojunction immobilized over a flexible support (ACF) resulting in excellent photodegradation of targeted pollutant (antipyrine) under visible light irradiation. The challenge lies in how to control immobilization of the photocatalyst over ACF along with good stability of the photocatalyst under flow conditions.
In your opinion, what are the most important questions to be asked/answered in this field of research?
Recently, the global community is paying more attention to environmental issues e.g., water shortage, air quality, climate change, microplastics and emerging pollutants. In my opinion, the most important question is developing low-cost, environmentally friendly functional materials and their effective utilization at the reactor scale for the rapidly expanding multidisciplinary environmental research field.
Can you share one piece of career-related advice or wisdom with other early career scientists?
Select a research problem which you are most passionate about, give your best and learn from failures without getting discouraged.
