中文摘要	mesoporous spinel nico2o4 nanoparticles were synthesized via a simple hydrothermal strategy. their physicochemical properties were characterized by x-ray diffraction (xrd), scanning electron microscopy-energy dispersive x-ray spectra (sem-eds), x-ray photoelectron spectra (xps) and nitrogen sorption measurements. their electrocatalytic performances were investigated by cyclic voltammetry (cv), chronoamperomerty (ca) and electrochemical impedance spectroscopy (eis) tests. the obtained nico2o4 materials exhibit a particle size of about 200 nm, a specific surface area (ssa) of 88.94 m(2) g(-1) and a mesopore volume of 0.195 cm(3) g(-1). the binary electroactive sites of co and ni species, high electron conductivity and intriguing mesoporous structures of the nico2o4 electrode favor its desirable electro-catalytic activity. a current density of 93 ma cm(-2) at 0.6 v in 1 m koh and 0.5 m ch3oh electrolytes was obtained for ch3oh electro-oxidation, and a current density of 130 ma cm(-2) at -0.3 v in 3 m naoh and 0.5 m h2o2 electrolytes was achieved for h2o2 electro-reduction. moreover, the nico2o4 electrode exhibits a high stability for both catalytic reactions, showing the potential for further development of high performance non-pt catalysts based alkaline fuel cells (afcs).
