摘要

用电子束辐照法在TiO2薄膜表面沉积Ag

Pt纳米颗粒

或对TiO2薄膜进行V+或Cr+离子注入

以提高TiO2薄膜的光催化效率

并将其响应波段拓展到可见光区域。通过X射线衍射（XRD）、扫描电镜（SEM）、X射线能谱仪（EDS）技术研究了改性TiO2薄膜。结果表明

电子束辐照可在TiO2薄膜表面形成纳米颗粒

注入离子分布于整个TiO2薄膜。光催化实验表明

这两种改性技术都能有效地提高TiO2薄膜在可见光下的光催化能力。

Abstract

Electron beam irradiation and ion implantation were used to improve photocataltsis efficiency of TiO2 films under visible light. NanomaterAg or Pt particles were formed on TiO2 films immerged in AgNO3 or H2PtCl6 solution and irradiated by 5 MeV E-beams. Other TiO2 films were implanted with 40 kV V+ or Cr+ ions. The films were characterized by scanning electron microscopy and depth profiling of the implanted species was determined by energy dispersive spectroscopy on cross section of the films. Higher photo catalytic efficiencies were found in the TiO2 films prepared by both the methods.
