Recent Advances in Polymer-Based Photocatalysts for Environmental Remediation and Energy Conversion: A Review

Photocatalysis is a crucial technique for environmental cleanup and renewable energy generation. Polymer-based photocatalysts have attracted interest due to their adaptability, adjustable chemical characteristics, and enhanced light absorption efficiency. Unlike traditional inorganic photocatalysts, we can optimize polymeric systems to enhance photocatalytic efficiency and yield significant advantages in environmental remediation and energy conversion applications. This study talks about the latest developments in polymer-based photocatalysts and how important they are for cleaning water, breaking down pollutants, and making renewable energy through processes like hydrogen production and CO2 reduction. These materials are proficient in degrading harmful pollutants such as organic colours, insecticides, and medications, transforming them into innocuous byproducts. Moreover, its use in solar-driven water splitting for hydrogen production and CO2 reduction provides a sustainable solution to global energy and environmental issues. These photocatalysts are much more effective and last longer thanks to progress in polymer chemistry, nano-structuring, and hybridization with materials like semiconductors and metal nanoparticles. The research underscores the promise of polymer photocatalysts for extensive environmental applications due to their cost-efficiency, ease of separation, and reusability. Future research endeavors seek to optimize polymeric photocatalyst systems for improved stability and performance, hence advancing sustainable solutions for critical environmental and energy challenges.
