Transition metal metaphosphates and noble phosphides prepared under similar conditions are potential hybrid catalysts for electrocatalytic water splitting, which is of great significance H2 production. Herein, the structure activity different species (i.e., Rh, Pd, Ir) on CoNiP4O12 nanoarrays have been systematically studied. Due to formation energies phosphides, Rh (RhPx) Pd (PdPx) as well Ir obtained same phosphorylation perspectively. RhPx/CoNiP4O12 PdPx/CoNiP4O12 exhibit much better HER than Ir/CoNiP4O12 due advantages phosphides. Density functional theory (DFT) calculations reveal that extraordinary originated from strong affinity H2O optimal adsorption H*. The best only requires a low overpotential 30 234 mV deliver 10 mA cm–2 OER, respectively, therefore effective overall splitting (requiring 1.57 V achieve current density cm–2). This work not develops novel electrocatalyst but also provides deep insight into mechanism

Abstract How to manipulate heterostructure engineering achieve high‐efficiency oxygen evolution reaction (OER) remains a significant challenge. Herein, promising OER electrocatalyst with IrNi nanoalloys (≈3.29 ± 0.12 nm) anchored on NiFe‐MOFs (IrNi@NiFe‐MOFs), exhibiting promoted phase transformation and self‐optimized dynamic interface electronic structure, via one‐step hydrothermal method is designed developed. Specifically, IrNi@NiFe‐MOFs displays excellent performance low overpotential of 228 mV at 10 mA cm −2 , small Tafel slope 37.6 dec −1 robust stability 100 . Experimental theoretical calculations identify the actual active sites as IrNi@NiFeOOH further reveal that structure electron by engineering, boost its catalytic performance. Moreover, strong interactions unique resulting in better charge redistribution adaptive bonding (Ir─O─Ni/Fe bonds). This therefore plays critical role promoting transfer, facilitating intermediates, reducing energy barrier potential‐determining step, thereby boosting These findings provide new insights into development MOF‐based electrocatalysts engineering.
