N2 - Energy generation through electrochemical conversion while addressing the environmental concerns has always been the topic of interest to the scientific community. Particularly, the development of low-cost and efficient electrocatalyst gained attention for large-scale energy and clean-energy production. But now the emphasis is on developing low-cost and efficient electrocatalyst materials that show more than one electrocatalytic reactions. Hence, we have developed a highly porous and active edge plane exposed β-Ni(OH)2 nanosheet on low-cost and flexible stainless-steel mesh (SSM) and investigated its catalytic activity for oxidation of urea, hydrazine, and water. The as-prepared β-Ni(OH)2/SSM demonstrates the excellent catalytic activity towards the urea oxidation reaction (UOR), hydrazine oxidation reaction (HzOR), and oxygen evolution reaction (OER) with potential lower than the 1.45 V vs. RHE, 1.34 V vs. RHE, and 1.51 V vs. RHE at 50 mA/cm2 current density, respectively. Furthermore, the as-prepared electrocatalyst demonstrates excellent stability in UOR, HzOR, and OER for long time. The promising electrocatalytic activity of as-prepared β-Ni(OH)2/SSM electrocatalyst is attributed to the highly porous, and edge plane exposed binder-free thin nanosheets grown on SSM, which also adds to the mechanical structure stability and a large amount of mass transportation during electrocatalytic activity.
