| 英文摘要 | 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. copyright (c) 2001 john wiley & sons, ltd. |
