Abstract Nowadays, the sluggish hydrogen evolution reaction (HER) and oxygen (OER) kinetics are key obstacles limiting commercial application of water splitting. In this study, a size‐matching strategy is proposed to construct molybdenum‐doped CoS 2 polyhedra (Mo‐CoS ) by encapsulating polyoxometalate (POM, H 3 PMo 12 O 40 guests into mesoporous zeolite imidazolium framework‐67 (ZIF‐67), with thioacetamide (TAA) serving as gentle sulfur source. The catalyst exhibits pronounced hollow structure due synergistic etching effects POM TAA, which can increase number active sites. Additionally, incorporation Mo optimizes electronic structure, thereby improving both HER OER performance. alkaline electrolytes, Mo‐CoS delivers an overpotential 330 mV 269 for HER, respectively, produce current density 100 mA cm −2 . Moreover, demonstrates exceptional performance in overall splitting, achieving cell voltage 1.55 V at 10 , along outstanding long‐term stability. This study provides promising avenue structural component optimization cobalt sulfide, could significantly improve efficiency production.

Abstract Interfacial engineering plays a key role in enhancing the performance of electrocatalysts for oxygen evolution reaction (OER). In this study, we report development hierarchical heterostructure composed iron oxysulfides integrated with MoS₂ on nickel foam (Fe‐SO@MoS 2 /NF) to serve as an advanced OER electrocatalyst. The vertically aligned morphology by growing layered can facilitate efficient mass transport, accelerate kinetic and improve ion diffusion at catalyst‐electrolyte interface. Surface modification interface is favorable improving conductivity boosting catalytic activity. Electrochemical measurements reveal that optimized demonstrates superior performance, low overpotential 253 mV 10 mA cm −2 Tafel slope 62.1 dec −1 . enhanced activity be attributed well‐engineered between MoS₂, which promotes rapid electron transfer stabilizes catalyst under operational conditions. Furthermore, long term stability alkaline conditions highlights its potential industrial water‐splitting applications. This work gives comprehensive understanding interfacial heterostructures opens new avenues designing transition metal oxysulfides‐based electrocatalysts.
