Recent Advances in Polymer-Based Photocatalytic Composites for Efficient Water Treatment: A Comprehensive Review

Abstract

The increasing demand for effective water purification technologies has led to significant research on polymer composites with enhanced photocatalytic properties. This literature review explores recent advancements in the development of polymer-based composites, particularly those incorporating photocatalytic materials such as ZnO, TiO₂, g-C₃N₄, graphene derivatives, and transition metal oxides. Studies have demonstrated that integrating these materials with polymer matrices like PVDF, PS, PES, and their combinations substantially improves photocatalytic activity, hydrophilicity, antifouling properties, and mechanical strength. Various synthesis techniques, including electrospinning, sol-gel processes, hydrothermal methods, and phase inversion, have been employed to fabricate these composites with controlled morphology and surface characteristics. The synergistic effects of photocatalysis and adsorption have shown remarkable efficiency in degrading organic pollutants, dyes, pharmaceutical residues, and oils from contaminated water sources. However, the literature also highlights challenges such as particle agglomeration, stability concerns, and process scalability. The review identifies key research gaps, particularly in enhancing cyclic stability, optimizing doping concentrations, and developing composites with superior recyclability and performance under visible light. This study provides a consolidated understanding of the existing research landscape, paving the way for future development of high-performance, reusable polymer composite photocatalysts for environmental remediation.
