一种具有微纳孔隙结构的二氧化钛多孔膜层光催化系统
Study on a Porous Titanium Dioxide Film Photocatalytic System with Micro-nano Pores Structure
摘要
Abstract
A porous anatase TiO2 film with nano and sub-micro pores was fabricated by sol-gel method with ion implantation. A dense film was firstly fabricated by the conventional sol-gel method, which was then bombed by Fe ion with a certain kinetic energy to generate a great amount of micro-nano pores. These micro-nano pores significantly enlarge the specific surface area of the titanium dioxide film. The experimental results of photocatalytic decomposition of a methyl orange solution display that the porous film is better than the dense film for the photocatalysis both under ultraviolet light and under visible light.关键词
