Homogeneous photocatalysts immobilized on polymeric supports: environmental and chemical synthesis applications

The interest in homogeneous photocatalysis arises from the high activity and selectivity advantages of controlled photochemical transformations such as synthesis of chemical/pharmaceutical products or complete degradation/mineralization of hazardous compounds. However, the major drawback of homogeneous photocatalytic reactions lies in the separation and recovery of the photocatalyst after the reaction, necessary to make the photocatalytic process eco-friendly. Immobilization of homogeneous photocatalysts on different supports is considered to be a viable method to increase the retainability and reusability of the photocatalyst simultaneously. This chapter aims to provide an in-depth information related to the immobilization of various homogeneous photocatalysts on well-known synthetic and natural polymers. Detailed information related to the potential environmental and chemical synthesis applications of immobilized homogeneous photocatalysts are also discussed. Finally, this chapter concludes with a new direction in emerging technologies for developing better supported photocatalysts. © 2021 Elsevier Inc.
