二氧化钛光催化氧化技术的研究进展

Research Progress in TiO_2 Photocatalytic Oxidation

在阐明光催化氧化反应机理的基础上分析了国内外TiO2光催化氧化反应的研究现状。提出目前国内外主要是从TiO2负载基材、TiO2光催化剂的修饰、改性以及TiO2光催化反应的影响参数几个方面进行研究,指出某些掺杂金属或非金属的TiO2光催化剂可使TiO2薄膜的吸光范围拓宽至可见光区,具有良好的应用前景。

The status quo of research about TiO2 photocatalytic oxidation reaction at home and abroad was analyzed on the basis of stating photocatalytic oxidation reaction mechanism. It was proposed that the major reasreaches were about TiO2 ＇s loading substrate and modification of TiO2, and several impact parameters of photocatalytic reaction, and it was pointed out that some of the non - metallic or metal - doped TiO2 photocatalyst can expand the absorption scope of TiO2 films to visible light scope, and that has a good application prospect.
