摘　　要：研究了稀土促进剂对ＣＯ＋Ｈ２合成二碳含氧化合物的Ｒｈ／ＳｉＯ２催化剂反应性能的影响，并用ＴＰＲ、Ｈ２－ＴＰＤ。Rh catalysts with rare earth elements as promoters were evaluated by CO+H 2 reaction for synthesis of C 2 oxygenates and characterized by TPR,H 2 TPD and uptakes of CO and hydrogen. The results indicated that addition of rare earth elements obviously improved the activity and selectivity of the catalysts for synthesis of C 2 oxygenates from CO and H 2.The increase of activity and selectivity to C 2 oxygenates of the catalysts were correlated with the results of characterization.
