Graphitic carbon materials are employed in a range of catalytic processes including:
1. Heterogeneous Catalysis: In this type of catalysis, graphitic carbon materials serve as supports for metal nanoparticles. The high surface area and conductivity of graphitic carbon enhance the dispersion and stability of the metal nanoparticles, thereby improving the overall catalytic activity. 2. Electrocatalysis: Graphitic carbon materials are widely used in electrocatalysis for reactions such as the oxygen reduction reaction (ORR), hydrogen evolution reaction (HER), and oxygen evolution reaction (OER). Their excellent electrical conductivity and chemical robustness make them ideal components in electrodes for fuel cells and batteries. 3. Photocatalysis: In photocatalysis, graphitic carbon materials can be used as supports or co-catalysts to improve the efficiency of light-driven reactions, such as water splitting and organic pollutant degradation.
