Electrochemical studies in basic medium indicated that electrocatalytic splitting of hydrazine occurs at a much lower potential 0.2 V (vs Ag/AgCl) in copper-cobalt sulfide in comparison to cobalt sulfide. Gaseous analysis reveals formation of oxygen at near thermodynamic voltage of 1.23 V. Experimental observations revealed the influence of hydrazine electro-oxidation on water splitting reaction. Adsorption energy of N<inf>2</inf>H<inf>4</inf> on catalyst surface and projected density of states from computational studies using Density Function Theory (DFT) proved higher activity for copper-cobalt sulfide catalyst for the electrocatalytic splitting of Hydrazine. Plausible mechanism is depicted based upon the experimental observations.falseAdsorption | CuCo2S4 | DFT | Electrocatalyst | Hydrazine | Hydrazine electro-oxidation | ThiospinelArticle1 October 20223116776arJournal3WOS:000893964300008
