摘要: Photocatalytic process has been applied to the treatment of air pollutants. It is necessary enhance photocatalytic activity TiO2 and design system, for practical application. The aspects application were discussed. Various species, such as transition metal ion, noble metal, oxide, anion, could modify surface improve activity. Photoelectrocatalytic (PEC) system was very effective enhancement photoactivity by applying a high voltage onto surface. showed better decomposition various pollutants bacteria than photocatalysts. To apply photocatalysts in real environment, stable immobilization catalyst on substrates, steal plate, membrane, glass fiber, so on, important. Based these modified and/or immobilized TiO2, photocatalysis widely used air-cleaning systems.
