考察了ＴｉＯ_２和ＺｒＯ_２担载的铜基催化剂的结构及其催化甲醇脱氢的反应性能。氮吸附和ＥＸＡＦＳ结果显示，两个催化剂的结构性质以及铜所处的配位环境比较接近。但Ｘ-射线光电子能谱测试结果显示，催化剂Ｃｕ／ＴｉＯ_２中铜周围的电子密度较催化剂Ｃｕ／ＺｉＯ_２中的高。ＴｉＯ_２结果表明，ＴｉＯ_２能够降低与之接触的较大ＣｕＯ的还原温度。催化剂电子结构的不同导致反应性能的差异，在Ｃｕ／ＴｉＯ_２催化剂上甲酸甲酯是主要产物，而Ｃｕ／ＺｒＯ_２催化剂则催化甲醇深度脱氢生成ＣＯ。此外，Ｃｕ／ＺｒＯ_２催化剂失活较Ｃｕ／ＴｉＯ_２催化剂慢得多。
The structure of copper-based catalysts supported on TiO_2 and ZrO_2 and their catalytic performance for methanol dehydrogenation were investigated. The results of nitrogen adsorption and EXAFS show that the structural properties of the two catalysts and the coordination environment of copper are relatively close. However, the results of X-ray photoelectron spectroscopy showed that the electron density around Cu in catalyst Cu / TiO 2 was higher than that in Cu / ZiO 2 catalyst. The results of TiO 2 show that TiO 2 can reduce the reduction temperature of the larger CuO contacted with it. The difference of the electronic structure of the catalyst leads to the difference of the reaction performance. Methyl formate is the main product on the Cu / TiO 2 catalyst while the Cu / ZrO 2 catalyst catalyzes the deep dehydrogenation of methanol to CO. In addition, the Cu / ZrO 2 catalyst deactivated much slower than the Cu / TiO 2 catalyst.
