草酸盐胶体共沉淀法超细催化剂的后处理条件（焙烧温度）明显影响催化剂的性能，发现焙烧温度为３５０℃的催化剂活性最高。催化剂的结构分析表明，ＺｎＯ２和Ｃｕ４Ｏ３２种物相对催化剂活性有重要影响。
Oxalic acid colloidal coprecipitation superfine catalyst post-treatment conditions (calcination temperature) significantly affect the performance of the catalyst and found that the calcination temperature of 350 ℃ catalyst activity highest. Structural analysis of the catalyst showed that the relative activity of ZnO2 and Cu4O32 species had a significant effect.
