摘要： A CoCuxOy catalyst, the molar ratio of Co, Cu and O thereof being 1:(0.2-1):(3-4). A preparation method of the catalyst comprises: dropwise adding a solution of an oxidizing agent and an initiator into a mixed aqueous solution of copper nitrate and cobalt nitrate, filtering the mixed solution after ageing to obtain a black cake-like precipitate, and calcining the precipitate at 180°C to obtain the CoCuxOy catalyst. The present invention also provides a method for preparing 2,5-furandicarboxylic acid from the CoCuxOy catalyst prepared by said method. The preparation method of the CoCuxOy catalyst in the present invention has simple and convenient operations and mild conditions; the prepared catalyst has high catalytic efficiency; and using the catalyst for preparing 2,5-furandicarboxylic acid is characterized by high efficiency, easy separation, low costs, less pollution and the like.
