Supported Cu/CeO2 catalysts with various loadings prepared by a deposition–precipitation method are thoroughly investigated with a series of in situ characterization techniques. The catalyst surface contains metallic Cu0 and interfacial sites, with the latter acting as the key active sites for the methanol steam reforming reaction. Moreover, the structures of both sites dynamically change in response to various environmental conditions. The Cu0 sites on larger Cu particles are more prone to oxidation than those on small ones, and the Cu–Ov–Ce interfacial sites are partially oxidized during the MSR reaction.

甲醇蒸汽重整过程中Cu/CeO2催化剂的动力学
通过一系列原位表征技术对通过沉积-沉淀法制备的具有不同负载量的负载型Cu/CeO 2催化剂进行了深入研究。催化剂表面含有金属Cu 0和界面位点,后者是甲醇蒸汽重整反应的关键活性位点。此外,两个站点的结构都会随着各种环境条件而动态变化。较大Cu颗粒上的Cu 0位点比小颗粒上的更容易被氧化,并且Cu-O v -Ce界面位点在MSR反应过程中被部分氧化。
