Effective electronic tuning of Pt single atomsviaheterogeneous atomic coordination of (Co,Ni)(OH)2for efficient hydrogen evolution

Abstract

A Pt1/(Co,Ni)(OH)2/C single-atom electro-catalyst efficiently splits water for H2generation,viabalanced water-dissociation and H2-formation steps from the synergistic effect of surface-defective (Co,Ni)(OH)2and electronically tuned Pt sites.
