In general, nanotechnology can be understood as a technology of design, fabrication and applications of nanostructures and nanomaterials, as well as a fundamental understanding of the physical properties and phenomena of nanomaterials and nanostructures. In recent years the development of industries like textile, leather, paint, food, plastics, and cosmetics is enlarged and these industries are connected with the discarding of a vast number of organic pollutants which are harmful to microbes, aquatic systems, and human health by influencing the different parameters. So the fabrication of those nanomaterials (coupled or doped) to form heterojunctions provides an effective way to better harvest solar energy and facilitate charge separation and transfer, thus enhancing the photocatalytic activity and stability. We expect this review to provide a guideline for readers to gain a clear picture of the fabrication and application of different types of heterostructured photocatalysts. In this review, starting from the photocatalytic reaction mechanism and the preparation of the photocatalyst, we review the classification of current photocatalysts, preparation methods, a factor that affects photocatalytic reaction, characterization of photocatalysts, and the methods for improving photocatalytic performance. This review also aims to provide basic and comprehensive information on the industrialization of photocatalysis technology.
