Abstract

Semiconductor photocatalysis for environmental purification has received a lot of attention in that (1) it involves the chemical destruction of pollutants rather than physical phase transfer, (2) clean and cheap oxygen from the air is used as an oxidizing agent, (3) the reaction can be conducted at low level of organic compounds under ambient condition, and (4) solar energy can be utilized to initiate photocatalytic reaction. Much of the photocatalysis research has been summarized in several reviews and books (Hoffmann et al. 1995; Kamat 1993; Fox and Dulay 1993; Hagfeldt and Grätzel 1995; Ollis and Al-Ekabi 1993; Blake 1994; Kaneko and Okura 2002), and a number of environmental products (e.g. air and water purification devices) based on the photocatalytic oxidation technique have been commercialized.
