Atomically Interfacial Engineering on Molybdenum Nitride Quantum Dots Decorated N-doped Graphene for High-Rate and Stable Alkaline Hydrogen Production.

ABSTRACT: The development of low-cost, high-efficiency, and stable electrocatalysts for hydrogen evolution reaction (HER) under alkaline conditions is a key challenge in water electrolysis. Here, an interfacial engineering strategy that is capable of simultaneously regulating nanoscale structure, electronic structure, and interfacial structure of Mo₂ N quantum dots decorated on conductive N-doped graphene via codoping single-atom Al and O (denoted as AlO@Mo₂ N-NrGO) is reported. The conversion of Anderson polyoxometalates anion cluster ([AlMo₆ O₂₄ H₆ ]^3- , denoted as AlMo6) to Mo₂ N quantum dots not only result in the generation of more exposed active sites but also in situ codoping atomically dispersed Al and O, that can f
