The most abundant earth’s atmospheric gas “nitrogen” is an efficient source for electrochemical conversion to ammonia. This catalytic process can be operated on ambient conditions and aqueous electrolyte reaction medium. The rate of reaction particularly suffers from competitive hydrogen evolution reaction (HER) as the potential required from HER is much lower than NRR. In order to increase the kinetics and yield of nitrogen reduction reaction (NRR), designing suitable electrocatalyst is exceedingly important. For this purpose, we are utilizing sol-gel method synthesized Zn2V2O7 in which zinc metal provides structural stability while vanadium centre enables catalytic sites for the facile reduction of dinitrogen molecules. So far, Zn2V2O7 has been studied for other applications namely, electrochemical hydrogen storage, LEDs, alkaline and lithium-ion batteries, photocatalysis etc., but exploring the new insights into complex electrochemical reactions like e-NRR provides new opportunities and better understanding about the material itself.
