Abstract | The invention provides a preparation method of a catalyst for synthesizing methanol from carbon dioxide, which comprises the following steps: preparing a mixed solution of metal copper salt, metal zinc salt, metal magnesium salt and metal cerium salt, then adding cane sugar and zeolite powder, and uniformly stirring to obtain a mixture; introducing inert gas, stirring, and dropwise adding a sodium carbonate solution into the mixture for precipitation; after dropwise adding, continuously introducing inert gas for a period of time; and filtering, collecting a filter cake, washing, molding, roasting in an air-isolated manner, and performing hydrogen reduction to obtain the catalyst for synthesizing methanol from carbon dioxide. The method is easy to operate and mature in process, the cost of the catalyst can be remarkably reduced, the method is suitable for popularization and industrial use, and the obtained catalyst is excellent in performance.
