摘要（英）：

The invention provides a catalyst for synthesizing isobutanol from synthetic gas as well as a preparation method and an application thereof. The catalyst is prepared by a coprecipitation method. The catalyst comprises the following components in percentages by weight: 2-35% of CuO, 10-50% of ZrO2, 10-35% of MnO2, 4-25% of NiO, 3-15% of Fe2O3, 0.01-0.2% of oxide of alkali metal and 0.01-0.3% of oxide of precious metal, wherein the oxides of alkali metal and precious metal are added and used as auxiliary agents. In the condition that the reaction temperature is 400 DEG C, the pressure is 6MPa, the air speed of synthetic gas is 8000h<-1>, the proportion of methanol to isobutanol in liquid phase products is higher than 85%, and the proportion of isobutanol is higher than 29%.
