One-step formation of a hybrid material of graphene and porous Ni with highly active Ni(OH) used for glucose detection.

A hybrid material of graphene and porous Ni with highly active Ni(OH) was formed through a one-step electrochemical exfoliation assisted method. The porous Ni with a pore size of 2-10 micrometers obtained by a hydrogen bubble template method was used as the cathode while the graphite foil was used as the anode with only (NH)SO as the electrolyte. Both the high surface areas of porous Ni and the oxygen radicals in graphene favored the formation of the Ni(OH).
