摘　　要：The remarkable development of nanotechnology and nanoscience has greatly promoted the vigorous development of the field of nanomaterials.This study explores a porous cuboid Ni/NiO composite nanomaterial obtained by calcining NiC_(2)O_(4)·2H_(2)O under a N_(2)environment.The composite affords direct electrochemical activity and good electrocatalytic properties.Compared to uncalcined precursor,the porous Ni/NiO obtained after calcination exhibited higher catalytic activity for glucose oxidation with higher sensitivity.Moreover,because of its regular cube structure the as-synthesized Ni/NiO exhibited improved electrochemical stability.Such porous Ni/NiO nanocubes represent promising glucose catalyst with high sensitivity and selectivity,improved stability and fast amperometric response.
