What is the role of reduced graphene oxide (RGO) in enhancing catalytic performance?

Label:chem

Topic
Reduced graphene oxide (RGO) has unique structural and electronic properties that make it an efficient catalytic support material.
Answer
RGO enhances catalytic performance through several synergistic mechanisms. Its exfoliated 2D structure provides a high surface area for active site dispersion. Residual functional groups and defects act as anchoring points for metal nanoparticles or single-atom catalysts. The restored sp2 conjugated network significantly improves electrical conductivity, enabling rapid electron transfer during redox reactions. In hybrid composites, RGO acts as a conductive scaffold, preventing charge recombination and optimizing metal d-band centers for improved reaction kinetics.
