The invention provides a copper-based catalyst by use of thorium as an assistant for methanol synthesis and a preparation method thereof, and relates to the copper-based catalyst for methanol synthesis. The copper-based catalyst is prepared from the following ingredients by weight percent: 0.1-2% of thorium oxide, 25-75% of copper oxide, 20-55% of zinc oxide and the balance being aluminum oxide. A coprecipitation method is adopted for preparation, and the pore diameter, the activity and the thermal resistance of the catalyst for methanol synthesis are improved. Compared with the catalyst free of thorium oxide, the catalyst added with 0.2-0.5% of thorium oxide serving as the assistant has the advantages that the pore diameter is increased to 8.65-8.74nm from 6.91nm, the initial activity is improved by 15%-18%, and the activity after thermal resistance is improved by 7-13%; the thorium oxide doping method is simple and the doping amount is low.
