Methyl radicals react with platinum nanoparticles (NPs) suspended in aqueous solutions to form (Pt0-NPs)-(CH3)n as a stable major product. Hydrogen gas treatment of the Pt0-NPs affects the composition of the products and the surface reactions. The results clearly point out that pretreatment of Pt0-NPs and (Pt0-NPs)-(CH3)n with H2 considerably affects their reactions with methyl radicals. The implications of the results on catalytic processes are discussed.
