Polymer-Graphene Composites in Catalysis and Environmental Applications: Recent Advances, Mechanisms and Future Perspectives

초록

Polymer-graphene composites have emerged as an advantageous class of functional materials that combine the exceptional electrical, mechanical, and surface properties of graphene with the ability to be processed, modified, and made more flexible through polymers. Polymer-graphene composites have recently seen rapid growth in environmental applications, including water treatment, pollutant degradation, sensing, and energy-environment interfaces. This review critically examines recent advancements in polymer-graphene composites for catalysis (including photocatalysis, electrocatalysis, hydrogenation, and energy conversion) and environmental applications (such as water treatment, dye degradation, heavy-metal removal, and oil-water separation). There is considerable discussion about structure-property-performance relationships, catalytic and adsorption mechanisms, and the role of polymer matrices. Current challenges, scalability issues, and future research directions for sustainable, industrially viable polymer-graphene systems are highlighted.
