应用光电子能谱考察了合成甲醇共沉淀ＣｕＯ－ＺｎＯ－Ａｌ２Ｏ３催化剂与掺钒样品的表面状态及催化反应的活性中心，它们是存在于催化剂固体表面上的Ｃｕ＋或Ｃｕ０，且Ｃｕ＋的活性高于Ｃｕ０；促使Ｃｕ＋离子稳定存在的主要原因是Ｃｕ＋溶于ＺｎＯ形成固溶体，Ａｌ２Ｏ３掺杂于ＺｎＯ诱导产生正离子空位及形成非化学计量化合物Ｚｎ１＋ｘＯ（ｘ＞０）。铜基催化剂掺钒的作用在于Ｖ３＋离子比Ａｌ３＋离子极化能力强，从而使ＺｎＯ更易形成有利于活性体Ｃｕ＋稳定的正离子空位，同时也可能形成钒酸盐，从而提高了催化剂的热稳定性。
The surface states of CuO-ZnO-Al2O3 catalysts and vanadium-doped samples synthesized by methanol coprecipitation were investigated by photoelectron spectroscopy. They are Cu + or Cu0 existing on the solid surface of catalyst, and the activity of Cu + is higher than that of Cu0 The main reason for the existence of Cu + ions is that Cu + dissolves in ZnO to form a solid solution, and the addition of Al2O3 to ZnO induces the creation of positive ion vacancies and the formation of non-stoichiometric compounds Zn1 + xO (x> 0). Copper-based catalysts doped with vanadium is the role of V3 + ions than Al3 + ion polarization ability, so that ZnO is more conducive to the formation of Cu + active active ions stable positive ion vacancies, but also may form vanadate, thereby enhancing the thermal stability of the catalyst .
