Vigneshraaj A S

My research focuses on Electrocatalysis, particularly the design and synthesis of Metal-Organic Frameworks (MOFs) and MOF-derived materials as high-performance electrocatalysts. Currently, I am working on the electrooxidation of organic molecules as a sustainable alternative to the Oxygen Evolution Reaction (OER), employing in-situ Raman spectroscopy and Electrochemical Impedance Spectroscopy (EIS) to investigate the mechanistic differences between OER and organic molecule oxidation. Additionally, I am pursuing integrated oxygen electrocatalysis by combining OER and Oxygen Reduction Reaction (ORR), with the objective of extending this research toward Metal-Air Battery applications and device-level integration.
