Abstract

The Pt₁/Co₃O₄-c catalysts exhibit great catalytic activities in hydrolytic dehydrogenation of ammonia borane (AB) with a specific rate of 6035 mol_H₂ mol_Pt⁻¹ min⁻¹ at room temperature. In situ DRIFTS spectra and theoretical calculations illustrate the chemisorption form of H₃N–BH₃⋯Pt₁/Co₃O₄-c due to the electron depletion of single-atomic Pt species tailoring by supports.
