- W990101628 abstract "制备了对丙烯直接气相环氧化具有优良催化性能的Ag-MoO3／ZrO2催化剂，采用原位FT-IR技术研究了丙烯、环氧丙烷及丙烯和氧气混合气在载体和催化剂上的吸附及反应行为．研究表明，丙烯在ZrO2载体和20％Ag-4％MoO3／ZrO2催化剂上吸附后，均不发生化学反应，而环氧丙烷在ZrO2载体上吸附后于400℃发生开环反应，在20％Ag-4％MoO3／ZrO，催化剂上吸附后于300℃发生开环反应．当丙烯和氧气混合气在ZrO2载体上共吸附后，随着反应温度从室温升高至400℃，二者开始反应生成CO2和H2O；混合气在20％Ag-4％MoO3／ZrO2催化剂上共吸附后于350℃开始反应．对比非负载型Ag—MoO3催化剂的研究结果可见，ZrO2载体的存在使催化剂的活性下降的同时，提高了对产物环氧丙烷的选择性．" @default.
