Heterogeneous Nanocomposite-Photocatalysis for Water Purification : William Andrew : 9780323393102 : 0323393101 : 27 Apr 2015 : In Heterogeneous Nanocomposite-Photocatalysis for Water Purification, the authors introduce various heterogeneous photocatalysts based on novel nanostructures of metal oxide semiconductors and graphene used for water purification, including TiO2, Fe2O3, SnO2, WO3 and g-C3N4, and outlines their advantages and drawbacks. The nanocomposite-photocatalysts ZnO and CdS are compared with reduced graphene oxide (rGO), a rapidly growing materials system. The authors describe how the photocatalytic activity of known nanomaterials can be improved by modifying the structural and optical properties (i.e., phase composition). Introductory portion of the book includes a brief survey of all different kinds of heterogeneous photocatalystsDiscusses the possible photocatalysis mechanism occurring during the degradation of different toxic pollutantsProvides the photoelectrochemi
