中文摘要：

通过在真空条件下将氯铂酸的乙醇溶液引入到钛酸纳米管内，再经过热处理制备了镶嵌铂的纳米管钛酸（简写为PNTA）．X射线光电子能谱（XPS）表明氯铂酸大部分转变成pt^0和PtO，顺磁共振谱（ESR）表明在PNTA中生成了束缚单电子的氧空位，在紫外-可见扩散漫散射谱（DRS）谱上表现出对可见光有吸收能力．丙烯的可见光光催化氧化实验结果表明：在可见光激发下（A〉420nm），PNTA对丙烯的光催化去除反应具有活性．

英文摘要：

Pt-inserted nanotube titanic acid （abbr. PNTA） was prepared as follows： H2PtCl6 ethanol solution was filled into the titanic acid nanotubes and then annealed in air at 673 K for 3 h. X-ray photoelectron spectroscopy （XPS） showed that H2PtCl6 has been converted to Pt^0 and PtO. The result of electron spin resonance （ESR） revealed that there are single-electron-trapped oxygen vacancies to be formed in PNTA after heat treatment in air. Under visible light （ A 〉 420 nm）, propylene can be catalytically oxidized by PNTA in the presence of air.
