Hydrocarbon oxidation catalyst and preparation method thereof

The invention discloses a hydrocarbon oxidation catalyst and a preparation method thereof, and particularly relates to a catalyst for preparing maleic anhydride by taking benzene as a raw material through gas-solid phase catalytic oxidization reaction. The catalyst is papered into a solution or a suspended liquid by taking a salt or an oxide containing V, Mo, Ti, P, Na and Ni as a precursor through drying, activating, homogenizing, emulsifying and spraying. The hydrocarbon oxidation catalyst can be used for solving the problems that the existing catalyst is long in induction period, the active substances are easy to separate, the catalyst raw material utilization rate is low, the working environment of the worker is poor, and the environmental pollution is severe.
