Abstract
The photocatalytic removal of water contamination is a promising, eco-friendly, and advanced technique that captures and degrades the contaminants in the targeted products. The primary benefit of the photocatalytic removal of pollutants is their excellent stability, nontoxic nature, minimized mass transfer, effective utilization of solar irradiation, and ability to operate at room temperature. The catalytic fouling and recovery are the main drawbacks of the catalyst. Similarly, the materials’ photocatalytic properties play a vital role in the selection and performance of the material. The nanomaterial's size is directly proportional to its performance. The larger-sized photocatalyst possesses poor photocatalytic performance compared to the smaller-sized nanomaterial because smaller-sized nanomaterials possess a larger specific surface area and active sites. Additionally, the formation of a heterojunction of one material into another nanomaterial is an effective way to enhance the material's stability and catalytic performance. More precisely, the porous nature and existence of the active sites have a massive influence on the material's performance because the porous nature and extra active sites provide more interaction with the degraded pollutant and the nanomaterials. In this chapter, we discussed the photocatalytic performance of the various nanomaterials, advanced treatment methods for specific contaminants, and current and future challenges of treatment methods.
