摘要（英）：

The invention relates to a catalyst, in particular to the catalyst for hydrogenation of carbon dioxide to generate methanol and a preparation method thereof. A carbon nanotube-based material is adopted as an accelerating agent. When being used for the catalytic hydrogenation of the carbon dioxide to generate the methanol, the catalyst can effectively increase the hydrogenation converting rate of the carbon dioxide and the one-path yield rate of the methanol. The catalyst comprises main metal components and the accelerating agent of the carbon nanotube-based material. The main metal components include Cu, Zn and Or. The accelerating agent of the carbon nanotube-based material means CNT or y% Co/CNT, and the chemical formula is CuiZnjZrk-x% (CNT or y% Co/CNT). The mass percent of each component is as follows: Zn: 5 to 20%; Zr: 25 to 50%; the accelerating agent of the carbon nanotube-based material: 1 to 18%; and the rest is Cu. The catalyst is prepared through coprecipitation. A multi-wall carbon nanotube modified by metal cobalt is prepared by utilizing liquid-phase microwaves of polyalcohol to assist in chemical reduction and deposition.
