| Popis: | Silica supported silver nanoparticles (Ag°–SiO 2 –NCs, NCs=nanocomposites) suspended in aqueous solutions are efficient catalysts for the dimerization of methyl radicals to produce ethane, while bare silica is quite inert towards the interaction with methyl radicals. In the presence of small amounts of ethanol adsorbed on the SiO 2 surface, the reaction path with methyl radicals is changed and methane is formed as the major product. |
