Recent Development of Photocatalytic Application Towards Wastewater Treatment

Abstract

With increasing population levels and rapidly growing industries worldwide, the purification of water contaminated with different impurities is one of the biggest challenges we face in recent times. Photocatalysis holds great potential as an efficient mineralization process to remove the foreign matter present in wastewater. Rapid advancement in innovative materials development has made photocatalysis the frontrunner among different water treatment methods. Our main priority lies in different strategic approaches to improve photocatalytic performance. This review discusses the recent breakthrough in implementing the photocatalytic mechanism for successful wastewater treatment. Challenges and future prospects in this technological field have also been discussed.

Photocatalytic Dye Degradation from Textile Wastewater: A Review

“…Investigating metal-oxide-based semiconductors, including TiO 2 , SnO 2 , CeO 2 , ZrO 2 , WO 3 , and ZnO, researchers aim to leverage these photocatalysts in degrading organic pollutants within wastewater. 93,94 In their 2023 study, Mei et al investigated the challenges still preventing the widespread use of photocatalytic wastewater treatment technology in industries. They found that even though scientists have been working on photocatalysis for over three decades it is still not widely used because of various challenges.…”
