Inorganic nanoparticles (NPs) confined in carbon nanotubes (MWCNTs) will provide significantly improved performances compared to their counterparts supported on the outer walls of MWCNTs. In this paper, supercritical CO2 (sc-CO2) was used as an impregnation medium to assist the inorganic Ru precursor into the inner pores of MWCNTs. MWCNTs inner space confined Ru-MWCNTs nanocomposites were obtained after further reduction by H-2. The Ru-MWCNTs show excellent catalytic performance in the hydrogenation of D-glucose. The activity and stability of the prepared Ru catalyst were much improved. This sc-CO2 assisted impregnation is an effective and environmental benign process to prepare other metal NPs confined in MWCNTs as advanced functional materials.
