The development of efficient and Earth-abundant electrocatalysts for the oxygen evolution reaction (OER) is an urgent requirement in field electrochemical water splitting. electrocatalytic performance OER can be greatly enhanced by synergistic combination zeolite imidazolate frameworks (ZIFs) transition-metal phosphides, both which individually exhibit promising capabilities this regard. In study, a novel amorphous NiCoP deposited on ZIF-67 sheets supported Ni foam (labeled as NiCoP/ZIF-67/NF) material was successfully synthesized using simple, secure, time-efficient two-step strategy. experimental results demonstrate that NiCoP/ZIF-67/NF possesses large active surface area with abundant sites. Also, effect interaction between ZIF-67, well Co within NiCoP, effectively enhance its under alkaline conditions. Consequently, exhibits outstanding catalytic activity overpotential (η) 175 mV at current density 10 mA cm

Abstract Controlled and optimized heterogenic interfacial coupling is the key to enhance electrochemical performance. Herein, for first time, telluride‐based Co 9 S 8 /CoTe 2 heterostructure reported as a bifunctional catalyst energy‐efficient H generation. Detailed investigations suggest that leads superior performance of heterostructure. Furthermore, it displays excellent hydrazine oxidation reaction (HzOR) at industrial‐level current density (500 mA cm −2 @ 338 mV) using an electrochemically neutral carbon paper substrate. The overall electrooxidation‐assisted water splitting (OHzWS) cell couple 10 0.22 V, which 1.60 V less than conventional splitting. Band energy profiles reveal n‐n type heterojunction formation between CoTe phases. work function difference phases results in impulsive electron flow from phase creation built‐in electric field. This prompts kinetics HzOR hydrogen evolution (HER) by enabling faster charge transport interface. DFT supports experimental findings, Gibbs's free profile studies indicate interface favorable compared .
