The International Energy Association (IEA) reported the global demand for energy to be around 18,000,000 megawatts in 2013. This demand is expected to rise to around 25 TW in 2040. In addition, with an ever increase rise in global population combined with impending climate change, major concerns have been raised over the security of our energy future. Developing sustainable, renewable energy might play a major role in providing the resources that are needed to make the products we use on a daily basis. One way to achieve this goal is to develop electrochemical processes that can convert molecules in the atmosphere (e.g., water, carbon dioxide, and nitrogen) into higher-value products (e.g., hydrogen, hydrocarbons, oxygenates, and ammonia) by electro-catalysis. These electro-catalysts play a significant role in most of these energy conversion technologies because they increase the rate, efficiency, and selectivity of the chemical transformations involved. In this newsletter, we will highlight some of the recent contributions made by India’s leading institutes and research centers for electro-catalysis.

Oxygen Reduction Reaction (ORR) for Fuel Cell Cathode Catalysis

“Anchoring of ultrafine Co3O4 nanoparticles on Multi-walled Carbon Nano-Tubes (MWCNT) using supercritical fluid processing and its performance evaluation towards electro catalytic oxygen reduction reaction.” – J. Catalysis Science & Technology, Issue: 7, Page: 1227, Year: 2017

Prof. Rangasamy Thangamuthu and his co-workers (CSIR-Central Electrochemical Research Institute, Karaikudi) have synthesized novel MWCNT based electro-catalysts for ORR studies. The rotating-ring disk electrode (RRDE) measurements were conducted in fully automated fashion on PGSTAT 302 equipped with internal bi-potentiostat.

Hydrogen Evolution Reaction (HER) in Water Splitting for Hydrogen Storage

“Co-Mo-B Nanoparticles as a non-precious and efficient Bi-functional Electrocatalyst for Hydrogen and Oxygen Evolution.” - Electrochimica Acta, Issue: 232, Year: 2017, Page: 64–71

For the first time, Prof. S Gupta (University of Mumbai) and his team in collaboration with Prof. A Miotello (Università degli Studi di) have successfully synthesized a dual function electro-catalyst that could effectively catalyze both, hydrogen evolution as well as oxygen generation reactions. The measurements such as linear sweep with varying scan, tafel plots and polarization curves were recorded in time-effective fashion using PGSTAT 302 equipped with internal impedance module.
