- Abstract:The supported amorphous alloy catalysts Ni-Co-P/γ-Al<inf>2</inf>O<inf>3</inf>were synthesized by electroless plating for hydrogen generation from catalytic hydrolysis of sodium borohydride solution. The influences of deposition time, pH, NaBH<inf>4</inf>concentration and the Co/Ni atomic ratio on the hydrogen generation rate were investigated in this paper. The reported work also includes the full experimental details for the collection of a wealth of kinetic data to determine the activation energy (E<inf>a</inf>= 52.05 kJ mol<sup>-1</sup>). Energy dispersive X-ray spectrometer (EDS), field emission scanning electron Microscope (SEM), inductively coupled plasma-atomic emission spectrometer (ICP-AES) and X-ray diffraction (XRD), nitrogen adsorption-desorption isotherm were used to characterize surface element composition, morphology and structure of the amorphous alloy. © 2014, Hydrogen Energy Publications, LLC.
