A stable Ni-B catalyst in hydrogen generation via NaBH(4) hydrolysis

Abstract

We provided a more stable and physically adhesive Ni-B catalyst onto a porous Ni support via a simple dipping-chemical reduction process without additional heat treatment. The morphology and the crystalline of the catalyst were found to be strongly dependent on the concentrations of Ni precursor and reductant. A steady-state production rate of hydrogen from NaBH(4) is observed in the absence of mass loss of Ni-B catalyst and the activation energy of Ni-B for hydrogen production is comparable to that of other Ni composites.
