Abstract

Efficient and stable photocatalysts must satisfy some critical requirements: (1) the semiconductor must have a bandgap large enough to provide energetic electrons, but small enough to allow for efficient absorption overlap with the solar spectrum (1.23 eV ≤ Eg ≤ 3.0 eV, typically Eg > 2.0 eV); (2) there must be a mechanism to efficiently drive the charge separation and transportation processes. From this viewpoint, it is important to obtain photocatalysts with high photoefficiency. This chapter describes the synthetic methods of unitary metal oxide semiconductors (TiO2, WO3, ZnO, Fe3O3, Ta2O5, and CuO), heterojunction photocatalysts, and composite-based materials. Their structure, surface properties, and photocatalytic activity are also discussed.
