| 英文摘要 | silica-supported rh catalysts with different rh particle dimensions were investigated for co hydrogenation. the catalysts were characterized by various techniques such as tem, h-2-tpr and n-2 adsorption to study the catalyst morphology, the size distributions of rh particles and the silica pores. it was found that the distribution and the size of rh particles were affected by the silica pores, and the metal grains were enclosed in the pores of the support, and thereby their growth was limited. the catalytic activity and selectivity to c-2-oxygenates for co hydrogenation were found to be significantly controlled by the rh particle sizes, and the higher activity and selectivity to c2-oxygenates were obtained over bigger rh particles, within the range of the reported particle sizes. |
