Abstract：Mesoporous Co3O4-NiO catalyst was prepared by one-step thermal decomposition with the help of starch and nitrate as metal source.The reduction performance of the catalyst was characterized by hydrogen temperature programmed reduction(H2-TPR)analysis under three different heating rates.The initial reduction activation energy was calculated to be 43.6 kJ·mol-1.The initial reduction activation energy of bulk phase cobalt oxide and bulk phase nickel oxide catalysts is 47.9 kJ·mol-1 and 49.6 kJ·mol-1,respectively.The decrease of the reduction activation energy of mesoporous Co-Ni catalyst is related to the particle dispersion and interaction on the catalyst surface.The study of its reductive properties can provide some reference for the study of catalytic mechanism by H2-TPR method.
