摘　　要：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~à.A maximum turnover frequency(TOF)of 50.3 mol_(H2)mol^(à1)_(total metal)min^(à1)(135.6 mol_(H2)mol_(Cu)^(à1)min^(à1))was achieved at ambient temperature,which is superior to those of previously reported Fe or Cu based systems.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~à.A maximum turnover frequency(TOF)of 50.3 mol_(H2)mol^(à1)_(total metal)min^(à1)(135.6 mol_(H2)mol_(Cu)^(à1)min^(à1))was achieved at ambient temperature,which is superior to those of previously reported Fe or Cu based systems.
