Electron Shuttling of Ni–Phosphate–Co Bridging Enables the Bidirectional Valence Modulation for Superior and Ultralong Water Splitting for Sustainable Green Hydrogen Production

The high-energy barrier and sluggish kinetics hinder the conversion efficiency of electrocatalytic water splitting. These limitations can be mitigated by modulating the valence states of active sites in nonprecious metal catalysts. However, achieving the synchronous but opposite valence regulation o...
