| 摘 要： | 用程序升温脱附－红外光谱（ＴＰＤ－ＩＲ）动态方法，研究了铑与载互使用对铑催化剂上的ＣＯ孪生，线工和桥式吸附态稳定性的影响。结果表明，金属载体的非强相互作用（ＮＳＭＳＩ）能提高铑催化剂上３种ＣＯ吸附态的稳定性。其影响可用ＮＳＭＳＩ效应的酸－碱机制解释。

| Abstract: | The influence of metal- support interaction on the stability of adsorbed CO on somerhodium catalysts have been investigated by TPD-IR dynamic method. The results show that thenon-strong metal- support interaction(NSMSI)can enhance the stability of the gem -dicarbonyl,linear and bridged monocarbonyl species on the rhodium catalysts.This effect can be explained bymeans of the acid-base mechanism of NSMSI |
