英文摘要 | highly active and highly dispersed pd-loaded nano-catalysts using mercapto group (-sh) functionalized mesoporous silica supports, namely, pd-sh-mcm-41 and pd-sh-sba-15, were prepared using an impregnation-reduction approach. the surface -sh groups are believed to facilitate the high distribution and immobilization of the pd nanoparticles within the silica supports through an anchoring interaction. the catalysts featured long-range ordered structures, uniform pore size, high surface area, and highly dispersed pd nanoparticles as characterized by x-ray diffraction, n-2 adsorption-desorption, and transmission electron microscopy. the catalysts showed activity five times higher than that of commercial pd/c catalyst and three times higher than those of pd/mcm-41 and pd/sba-15 catalysts. within 1 h of reaction at 80 degrees c and 1.0 mpa, the conversion of phenol attained was greater than 99%, and the selectivity for cyclohexanone was 98%.
