应用ＸＰＳ能谱技术和合成气中压反应等对醇合成用铜钴基催化体系进行了表征研究。还原后的铜钴催化剂样品表面上钴以ＣＯ￣２＋和ＣＯ￣０形式共存，铜主要是Ｃｕ￣０物种。在反应条件下处理后，发生了再氧化现象，即钴主要以Ｃ０￣２＋形式存在，铜变为Ｃｕ￣＋或Ｃｕ￣δ＋物种。从催化剂的ＸＰＳ和ＸＡＥＳ结果可知，铜和钴之间具有强的相互作用和电荷转移。改良铜钴催化剂具有良好的醇合成的反应活性和碳链增长，助剂钼在样品还原后的表面状态主要是Ｍｏ￣６＋，同时也有少量的Ｍｏ￣５＋，Ｍ０￣￣４＋。在反应后主要是Ｍｏ￣６＋。 The characterization of copper-cobalt-based catalysts for alcohol synthesis was investigated by XPS spectroscopy and gas-phase synthesis of syngas. On the surface of the reduced copper-cobalt catalyst, cobalt coexisted in the form of CO 2 + and CO 2 O, and Cu was mainly Cu-0 species. Under the reaction conditions, the phenomenon of reoxidation occurs, that is, the main form of cobalt exists in the form of C0 +2 +, and Cu becomes Cu + or Cu + δ species. From the catalyst XPS and XAES results show that there is a strong interaction between copper and cobalt and charge transfer. The modified copper-cobalt catalyst has good reactivity of alcohol synthesis and carbon chain growth. The surface state of the auxiliary molybdenum after the sample is reduced is mainly Mo6 +, while a small amount of Mo5 +, Mo4 + is also present. After the reaction is mainly Mo ~ 6 +.
