Noble Metal Nanoparticles Anchored on Transition Metal Phosphides for Effective pH-Universal Hydrogen Evolution.

ABSTRACT: Constructing electrocatalysts with high activity and low precious metal content is essential for achieving efficient hydrogen production in pH-universal overall water splitting. Herein, five types of noble metal anchored transition metal phosphides are analyzed by theoretical derivation. Based on the calculation results, a suitable hybrid is screened out of Pt nanoparticles anchored on CoP nanowires (Pt─CoP) via robust Pt─P─Co bonds. This strong synergy between Pt and CoP through interfacial Pt─P─Co bonds optimizes the adsorption of key intermediates for hydrogen evolution reaction (HER) in a wide pH range from 0 to 14. Furthermore, strong interaction between Pt and CoP accompanied by a delicate structure reduces interfacial charge transfer resistance, creates abundant active sites, and en
