“…Heterogeneous photocatalysis appeared to be very effective since it can completely degrade dye effluents to less harmful substances such as H2O, CO2, etc., making it a very useful process for safely releasing textile wastewater into water bodies [62]. Lafta et al [36] incorporated phosphotungstic acid (PTA) upon metal-free graphitic carbon nitride (g-C3N4), which efficiently degraded more than 90% methyl violet dye (MV), present in wastewater at a pH value of 6.8, within a very short time. Such enhanced performance was attributed to PTA's high electron-hole separation efficiency.…”

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.

With the serious pollution of water resources in the process of social development, green and environmentally friendly photocatalytic technology has gradually attracted widespread attention. Though photocatalytic theory and technology are relatively mature, the current research is mainly focused on powders and less on the photocatalytic membranes, and few real practical cases of photocatalysis are studied. To summarize and update these advanced studies, this paper introduces the latest progress in photocatalytic membranes including discussing the differences of photocatalytic mechanism between free and fixed photocatalytic systems and the design philosophy of photocatalytic membranes. At the same time, some common fabrication methods, including in situ growth, coating, spinning, casting, and foaming methods are analyzed. Besides, the photocatalytic performances of different photocatalytic membranes in the actual environment and their use conditions are explored. Finally, a critical view of future trends is included. The explanation of the photocatalytic mechanism, large‐scale production, and the practicality of photocatalytic products are all problems that need to be solved in the future.
