Porous Ni/NiO nanohybrids for electrochemical catalytic glucose oxidation

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 NiC2O4 center dot 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.
