ＣＯ加氢反应机理是许多研究者感兴趣的课题．负载的Ｒｈ是ＣＯ加氢反应的优良催化剂．ＣＯ在Ｒｈ上吸附态的研究已有许多报道［１～７］，而对Ｈ２有关的吸附态的研究却少见报道．Ｗｏｒｌｅｙ等［８］利用高压超纯Ｈ２在２．２％Ｒｈ／Ａｌ２Ｏ３膜上首次观测到Ｒｈ—Ｈ...
The mechanism of CO hydrogenation reaction is a topic that many researchers are interested in. The supported Rh is an excellent catalyst for CO hydrogenation. There are many reports on the adsorption of CO on Rh [1-7], while the studies on the adsorption states of H2 are seldom reported. Worley et al [8] first observed Rh-H on 2.2% Rh / Al2O3 film using high-pressure ultra-pure H2
