## Abstract Two kinds of ultrafine CoβB amorphous alloy catalysts, denoted as Pβ1 CoβB and Pβ2W CoβB, were prepared by chemical reduction with borohydride in aqueous or 50% (v/v) ethanol/water solution, respectively. In comparison with the corresponding Coβbased crystalline catalysts and Niβbased c
