Abstract The occurrence of oxygen evolution reaction (OER) almost consumes most the electric energy hydrogen production by electrocatalytic water splitting. required in process electrochemical can be reduced choosing urea oxidation (UOR) instead OER. In this work, nickel hydroxysulfide is synthesized on foam (NiSOH/NF) and its performance was tested UOR. Experimental results show that vulcanization catalyst requires a low potential 1.38 V (vs RHE) to achieve current density 100 mA cm −2 an electrolyte containing 0.5 M urea, which 270 mV lower than conventional OER process. This innovative approach has yielded substantial reduction cell voltage necessary for overall splitting under two electrode system, thereby enhancing efficiency feasibility.

Abstract The quest for composite materials with unique features that each component, inherently, does not have is always an aspirational but challenging task. Among Transition metal oxides (TMOs), TiO 2 emerged as a prototype due to its earth abundance, environmental friendliness, and cost‐effectiveness, which has shown high activity photocatalytic hydrogen evolution. Unfortunately, inert electrocatalytic evolution reaction (HER) because it poor electrical conductivity unfavorable adsorption/desorption behavior. Herein the revitalization of overall water splitting, i.e., both HER oxygen (OER) reported by anchoring rutile‐anatase (a/r) nanoparticles on ‐OH/‐F terminated V 4 C 3 T x MXene, giving a/r @V heterostructure. synergetic effect showcases remarkable pH‐independent overpotential 35, 39, 82 mV in 0.5 m H SO , 1 KOH, phosphate‐buffered saline (PBS) respectively. catalyst also exhibits OER lowest 217, 267, 292 PBS respectively, outperforms pure . These findings, first time, support success anatase‐rutile MXene omnidirectional performance, low pH independence, pave avenue finding cost‐effective catalysts splitting.
