Abstract

Abstract: 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 Pt⁰ 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(λ>420 nm),propylene can be catalytically oxidized by PNTA in the presence of air.

Key words: Pt-inserted nanotube titanic acid, visible light photocatalysis, propylene removal
