【摘要】 用对硝基甲苯液相加氢生成对甲基苯胺为探针反应研究了碳纳米管负载铂锡催化剂的催化性能,分别评价了铂锡负载在碳纳米管、γ-Al2O3、SiO2上的催化活性。实验结果表明:在实验条件下,碳纳米管负载铂锡催化剂时反应物的转化率和产物的选择性分别是99.1%和100%。转化率分别是二氧化硅负载铂锡催化剂的1.5倍,三氧化二铝负载铂锡催化剂的1.8倍。更多还原

【Abstract】 The catalytic performance of PtSn-catalyst supported on carbon nanotubes was studied. The hydrogenation of p-nitrotoluene in liquid phase was used as the probe reaction in 500 ml autoclave. PtSn-catalyst supported on carbon nanotubes, SiO2 and γ-Al2O3 were evaluated respectively.The results showed that the conversion of p-nitrotoluene and the selectivity of p-toluidine were 99.1% and 100% over the carbon nanotubes supported PtSn-catalyst. The coversion was 1.5 and 1.8 times over the SiO2 and γ-Al2O3 supported Ptsn-catalyst respectively under our testing conditions.更多还原
