The high cost and low energy efficiency of conventional water electrolysis methods continue to restrict the widespread adoption green hydrogen. Anion exchange membrane (AEM) is a promising technology that can produce hydrogen using cost-effective transition-metal catalysts at efficiency. Herein, we investigate catalytic activity nickel iron nanoparticles dispersed on metal-oxide supports for oxygen evolution reaction (OER), employing electrochemical testing with an anion ionomer evaluate their potential application in AEM electrolyzers. We report performance NiFe varying Ni:Fe ratios CeO2 OER reaction, assessing overpotential, Tafel slope, stability catalysts. Our findings indicate Ni90Fe10 has highest as well stability. To further understand role different supports, assess electrocatalytic two more - TiO2 ZrO2. While lowest other also show good current densities. exhibits superior its overpotential after chronopotentiometry measurements approaches These results underscore critical addition enhancing nanoparticles' emphasize importance metal oxide improving catalyst performance.

Rationally optimizing the atomic and electronic structure of electrocatalysts is an effective strategy to improve activity electrocatalytic oxygen evolution reaction (OER), yet it remains challenging. In this work, heterointerface engineering developed accelerate OER by decorating iridium atoms on low-crystalline cobalt hydroxide nanosheets (Ir–Co(OH)x) via oxygen-coordinated bonds modulate local structure. Leveraging detailed spectroscopic characterizations, Ir species were proved promote charge transfer through Ir–O–Co coordination between atom Co(OH)x support. As a result, optimized Ir–Co(OH)x exhibits excellent with low overpotential 251 mV drive 10 mA cm–2, which 63 lower than that pristine Co(OH)x. The experimental results density functional theory calculations reveal isolated can regulate environment configuration Co(OH)x, thus accelerating catalytic kinetics. This work provides atomistic for modulation metal active sites in design high-performance electrocatalysts.

Abstract Efficient bifunctional electrocatalysts for hydrogen and oxygen evolution reactions (HER OER) play crucial roles in water electrolysis. However, the discrepancy binding affinities of catalytic sites to O/H‐contained intermediates makes it difficult achieve OER HER catalysis simultaneously. Multi‐component heterostructures have been demonstrated be an effective solution realize electrocatalysts, but division labor action mechanism each component are not fully elucidated. Therefore, based on asymmetrical crystal field stabilization energy (CFSE) between NiS Ni 2 P, heterogeneous catalyst (NiS/Ni P@NF) with built‐in electric (BEF) is constructed this paper, which showed efficient bifocal cracking. DFT calculation has confirmed that BEF causes directional movement electrons material, thus optimizing OER/HER reaction path. Further control experiments indicated P serves as active species corresponding HER, NiS/Ni P@NF delivers a remarkably reduced cell voltage 1.62 V (10 mA cm −2 ) within H‐type electrolyzer both anode cathode electrodes. The strategy constructing CFSE potential precisely induce local electron flow site accurately design multifunctional catalysts composition‐function contrast.
