摘　　要：利用聚乙二醇为分散剂,通过等体积浸渍法制备了负载铟(In)的不同氧化物催化剂,借助X线衍射(XRD)、比表面积(BET)和氧气(H_2)程序升温还原(H_2-TPR)等测试手段对催化剂进行了表征,并以甲醇重整制氢为探针反应考察了载体及铟含量(质量分数w,全文同)与反应性能之间的关系.结果表明:催化反应性能与载体种类及铟含量之间存在明显的相关性.相同铟负载量时,在选定的载体中氧化铁显示了最佳的甲醇转化率和氢气及二氧化碳(CO_2)选择性;同时以铁氧化合物为载体时,铟的最佳负载量为3.0%.With polyethylene glycol used as the dispersing agent, supported indium oxide catalysts were synthesized by incipient-wetness impregnation method, and characterized via X-ray diffraction（XRD）, BET specific surface area and H2 temperature program reduction （H2-TPR） technologies. The catalytic performance of the synthesized catalysts was evaluated by methanol steam reforming. The results indicate that the catalytic performance is depended on the supports and indium content. With the same indium content,indium loaded FeOx catalyst exhibits the optimal methanol conversion and the selectivity of H2 and CO2 ,and the optimal indium content is 3.0%.
