| 摘 要： | 以磷酸为原料，制备成型TiO2载体采用焙烧成型的方法, 考察制备过程中焙烧时间、焙烧温度、黏合剂配比等对TiO2成型载体性能的影响。采用X线衍射仪（XRD）、比表面检测定仪（BET）和扫描电子显微镜（SEM）等手段对载体进行表征。结果表明: 在干燥温度105 ℃、煅烧温度为800 ℃、煅烧时间4 h条件下，成型载体TiO2有利于催化剂活性物质的负载，且催化剂的载体主要以锐钛矿型TiO2晶型存在。

| Abstract: | Phosphoric acid solution was used as the raw material to make TiO2.The effects of adhesive proportion,calcination time,calcination temperature in the preparation process were investigated.The characteristics of the carrier were determined by using X-ray diffraction(XRD),surface detection system(BET) and scanning electron microscopy(SEM).The results showed that the carrier of the catalyst was in the form of anatase under the following conditions:drying temperature at 105 ℃,calcination temperature at 800 ℃,calcination time of 4 h. |
