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.

摘要： This invention relates to bifunctional catalyst formulation for synthesis of dimethyl-ether (DME) from waste carbon dioxide (CO2) and hydrogen (H2) and the preparation method of this catalyst formulation. In the preparation method, aluminum oxide-silicon dioxide-copper oxide (Al2O3-SiO2-CuO) catalyst mixture formulation is obtained by using the sol-gel method. The catalysts that are the subject of the invention are bifunctional and perform the synthesis of DME from CO2 and H2 in a single-step without forming unwanted byproduct of CH4, and thus, the synthesis of DME can be done much simply and economically. In addition to this, the sol-gel method in the current invention yields the controlled crystallite size of the active component in the catalysts; thus, the active site loss problem due to uncontrolled growth of crystal sizes that occurs in traditional preparation methods is prevented. The catalyst mixture formulation weight percentages are 10%-90% Al2O3, 10%-90% SiO2 and 10%-90% CuO.
