| 摘 要： | 本文用程序升温热脱附法和氢氧滴定法研究了SiO2、SiO2·Al2O3、Al2O3、SiO2·SnO2和Al2O3·SnO2等和Pt的相互作用,表明Pt和载体作用强弱的顺序为:Al2O3>SiO2·Al2O3>SiO2;发现SnO2具有强化SiO2和Al2O3载体效应的作用;提出Pt和载体相互作用较强部位可能是Pt和缺氧氧化物所形成的表面络合物--Pt-Al2Ox]和Pt-SnOx]。

| Abstract: | The interaction between Pt and carriers SiO2, SiO2-Al2O3, Al2O3, SiO2-SnO2 and Al2O3-SnO2 was investigated by TPD and HOT method. It was shown that the order of the Pt-carrier interaction strength is Al2O3>SiO2-Al2O3>SiO2; It was found too that the oxide of Sn Possesses the action to strengthen the carrier effect of SiO2 and Al2O3. On this basis, we suggested that the site of the Pt-carrier stronger interaction may be the surface complex of Pt and oxygen-dificient oxides Pt-(Al2Ox) and Pt-(SnOx). |
