Abstract

Herein, we first describe the physical mixture of Cu(OH)₂/Fe(OH)₃ as a composite catalyst precursor for the dehydrogenation of ammonia borane (AB) in methanol. During the initial period of catalytic reaction, Cu nanoparticles were formed in-situ. The catalytic activity of Cu nanoparticles can be significantly enhanced with the assistance of Fe species and OH^-. A maximum turnover frequency (TOF) of 50.3 mol_H₂ mol_{total metal}^-1 min^-1 (135.6 mol_H₂ mol_Cu^-1 min^-1) was achieved at ambient temperature, which is superior to those of previously reported Fe or Cu based systems.

Keywords: Ammonia borane; Cu(OH)(2); Dehydrogenation; Fe(OH)(3).
