<i>In situ</i>precise anchoring of Pt single atoms in spinel Mn₃O₄for a highly efficient hydrogen evolution reaction

Abstract

Controllable doping of a Pt single-atom into the octahedral sites of a spinel Mn 3 O 4 lattice leads to a moderate rise of the d-band-center, which guarantees the adsorption of key intermediates for superior hydrogen evolution reaction.
