Synthesis of Solid Superacid NiO-ZrO₂/SO₄^2- and Its Electrocatalytic Activity for Glucose Oxidation

Solid superacid NiO-ZrO2/SO42- was synthesized and its electrocatalytic activity for glucose oxidation were studied.The nanostructure was characterized by X-ray diffraction,scanning electron microscope and Fourier transform infrared spectroscopy.Its electrocatalytic activity for glucose oxidation was studied.It was shown that the catalytic effect was mainly caused by the active material of Ni in NiO-ZrO2/SO42-,and the electro-deficient metal centers of ZrO2/SO42- accelerated electron transfer rate during reaction process.Therefore,comparing with NiO/SO42-,the NiO-ZrO2/SO42- possessed lower peak potential and more satisfactory stability.
