TiO2, ZnO, and SnO2-based metal oxides for photocatalytic applications: principles and development

This review mainly relied on advanced TiO2, ZnO, and SnO2 nanostructures for photocatalysis; therefore, their physical and chemical properties are hereafter summarized. We will discuss the various approaches that have been already proposed such as the doping, the heterostructure fabrication, and the use of plasmonic materials. We wish to draw here a particular attention to the semiconductor/semiconductor heterostructures.
