Photocatalysis: Present, past and future

Thillai Sivakumar Natarajan and Rajesh J. Tayade

Photocatalysis is one of the effective catalytic processes with potential applications in solving the environmental pollution and energy crisis problems by degrading the pollutants, reducing the CO2 levels and production of sustainable hydrogen (H2) fuel, respectively, using semiconductors as a photocatalyst under irradiation of light. Various types of photocatalytic materials, reactors, and processes with efficient photocatalytic performance have been studied to fulfill the practical requirements. In this chapter, initially, we will briefly discuss the principle of photocatalysis, its application in pollutants abatements and energy production along with the basic requirements. Simultaneously, we will discuss the past and present state of art of the utilization of this potential technique in these applications. Finally we describe future viewpoint of this technique in these fields as well.
