Hierarchical NiCo / NiO / NiCo ₂ O ₄ composite formation by solvothermal reaction as a potential electrode material for hydrogen evolutions and asymmetric supercapacitors

Electrochemical energy storage and conversion mechanisms are highly viable routes in the current scenario, and hence supercapacitor and electrolysis of water splitting have gained significant attention in recent times. Thus, transition metal nickel cobalt oxides are widely inspected as promising electrode materials for electrocatalysis and supercapacitors. However, the pure NiCo2O4 was highly hindered by its widespread uses due to low electronic...
