Abstract

RuO₂-Au composite nanoparticles (RuO₂-Au CNPs) are synthesized via a simple calcination of RuNPs and AuNPs encapsulated within extra-large mesocages of mesoporous silica (EP-FDU-12). Both the Ru/Au ratio (0.02:0.2) and the nanostructure of the mesoporous supports are critical for its successful formation. Surface-enhanced Raman scattering (SERS) effects are observed for RuO₂ composite because of the interaction between RuO₂ and Au of the RuO₂-Au CNPs. The nanocontact modifies the electronic and chemical properties of Au and RuO₂, respectively, which in turn benefits their catalytic performance with enhanced activities and reduced coking-deposition content in gas-phase cyclohexanol-selective oxidation.
