Fabrication of Porous Nanocrystalline NiCo_2O_4 Electrode for Water Electrolysis

摘要

A porous nanocrystalline NiCo_2O_4 compound electrode was obtained.The morphology of the electrode was controlled by altering the concentration of precipitant (NaOH solution).The electrode was consisted of metal substrate (Ni) and porous nanocrystalline NiCo_2O_4 film which was stacked by homosized and pretty regular hexagonal nanoparticles,with thinner than 50 nm and about 200 nm in diameter.The electrode exhibits good electrochemical properties compared with Ni electrode.
