An introduction to photocatalysts and their applications

Abstract

This chapter introduces the fundamentals of photocatalysts and their role in the development of sustainable technologies. It explains the basic principles, mechanisms, and workings of photocatalysts for wastewater treatment and hydrogen generation. It also explores the different types of photocatalysts, including their characteristics and features at both the nanoscale and the microscale. The methods of synthesis and the importance of green synthesis compared to other conventional routes are discussed in detail. In addition, this chapter discusses some other important parameters reported in the research literature, such as the reusability and stability of photocatalysts, factors affecting the photocatalytic performance of photocatalysts, and the need for new and advanced strategies to improve the photocatalytic efficiency of photocatalysts for the production of energy and the development of environmentally friendly technology.
