Wastewater treatment: synthesis of effective photocatalysts through novel approaches

Treatment of wastewater and reusability of water systems are crucial aspects. Scientists are focusing on performing water treatment with environmentally friendly and cost-effective methodologies. Previously, sewage has been treated with various physical, chemical, and biological processes. Environmental scientists in this field have been applied to a new class of process called advanced oxidation processes predominantly by using heterogenous photo catalysis, which converts photon energy into chemical energy, for wastewater remediation (industrial, agricultural, and domestic runoff). The process of photocatalysis is getting attention as an effective wastewater treatment methodology due to its efficient degradation of diverse pollutants. Certainly, photocatalysis is an eco-friendly and competent process for wastewater remediation to resolve water pollution problems. In this chapter, we discuss novel approaches for preparing various forms of photocatalyst materials. Besides, the insight of the photocatalytic material properties and modifications on synthesis have been explained.
