摘要:The catalytic properties of Cu–Co–P/γ-Al<inf>2</inf>O<inf>3</inf>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/γ-Al<inf>2</inf>O<inf>3</inf>alloy catalyst was synthesized by electroless deposition. It was found that the as-prepared catalysts exhibited low activation energy (E<inf>a</inf> = 47.8 kJ mol<sup>−1</sup>) and good cycle properties in catalytic hydrolysis of NaBH<inf>4</inf>solution. The influences of NaOH and NaBH<inf>4</inf>concentration and temperature on hydrogen generation rate (HRG) were also investigated in this paper. © 2016 Hydrogen Energy Publications LLC
