• Abstract:The catalytic properties of Cu-Co-P/gamma-Al2O3 in hydrogen production via sodium borohydride hydrolysis were investigated on aspects of the surface morphology, structure and chemical composition. The characterization methods employed are X-ray diffraction (XRD), scanning electron microscope (SEM), inductively coupled plasma-atomic emission spectrometer (ICP-AES) and energy dispersive spectroscopy (EDS). The amorphous Cu-Co-P/gamma-Al2O3 alloy catalyst was synthesized by electroless deposition. It was found that the as. prepared catalysts exhibited low activation energy (E-a = 47.8 kJ mol(-1)) and good cycle properties in catalytic hydrolysis of NaBH4 solution. The influences of NaOH and NaBH4 concentration and temperature on hydrogen generation rate (HRG) were also investigated in this paper. (C) 2016 Hydrogen Energy Publications LLC.
