What are the Applications of Functionalized Graphene in Catalysis?
Functionalized graphene has shown promise in various catalytic applications: 1. Electrocatalysis: Functionalized graphene has been used extensively in electrocatalytic processes. For example, nitrogen-doped graphene has shown excellent performance in the oxygen reduction reaction (ORR), a crucial reaction in fuel cells. 2. Photocatalysis: Modified graphene can enhance the performance of photocatalytic materials by improving charge separation and light absorption. Titanium dioxide (TiO2) combined with functionalized graphene has been used for the degradation of organic pollutants under light irradiation. 3. Heterogeneous Catalysis: Functionalized graphene can serve as a support material for metal nanoparticles, enhancing their dispersion and stability. This has applications in hydrogenation reactions and other catalytic processes. 4. Biocatalysis: Functionalized graphene can immobilize enzymes, enhancing their stability and reusability for biochemical reactions.
