Beschreibung
Zusammenfassung:	Abstract The invention discloses a preparation method of a mesoporous supported catalyst CuO LaCoO3. Immersing the mesoporous LaCoO3 in copper nitrate solution, and calcinating the mesoporous LaCoO3 impregnated with Cu ions in muffle furnace at 400-600°C for 4-6 hours, so as to obtain the final CuO-LaCoO3. The raw materials required are simple and easy to obtain, and the preparation price is lower than that of precious metal catalysts. Components in the obtained CuO-LaCoO3 catalyst are uniformly dispersed and interact with each other, which shows good low-temperature catalytic activity and thermal stability against CO in exhaust gas, which can be applied in the field of automobile exhaust gas catalysis. The loading of CuO provides more active oxygen for the original catalyst, thus improving the low-temperature catalytic activity of the catalyst.
