An unorthodox intra-lattice ‘inverse’ charge transfer occurs from the undercoordinated Mo-center to neighbouring Ni-centers in the Ni73Mo alloy (−) and NiMo-hydroxide (+). The self-supported couple splits alkaline water at 1.48 V at 10 mA cm−

The prevalence of intermetallic charge transfer is a marvel for fine-tuning the electronic structure of the active centers in the electrocatalysts. Although, Pauling electronegativity is the primary deciding factor for the direction of charge transfe
