| 中文摘要 | Temperature-programmed surface reaction (TPSR), temperature-programmed reaction (TPR) and temperature-programmed desorption (TPD) were used to study the synthesis Of C-2-oxygenates from syngas over Rh-Mn-based catalysts supported on amorphous silica and mesoporous MCM-41 supports. Both TPD and TPSR reveal the existence of several different kinds of CO species on the catalyst surface in the course of the catalytic reaction (linear, geminal, bridged and tilt-adsorbed CO species) but only the bridged form and tilt-adsorbed CO species are the precursors for CO dissociation and the formation of C-2-oxygenates. The formation temperature of acetaldehyde is higher than that of ethanol, which suggests that they may be formed via different mechanisms. The ethanol formation activity over the Rh-Mn/MCM-41 catalyst is lower than that over the Rh-Mn/SiO2, which suggests that the number of active sites for ethanol formation are fewer on the surface of Rh-Mn/MCM-41. However, the acetaldehyde formation activities are almost identical for the Rh-Mn catalysts supported on amorphous SiO2 and MCM-41, meaning that acetaldehyde and ethanol might be formed on different active sites.
