摘    要:制备了负载型Ru-Co羰基簇催化剂,用X-ray光电子能谱(XPS)和程序升温脱羰(TPD)等技术,对负载型双金属簇催化剂的表面化学性质和不同气氛中的脱附产物进行了研究,发现负载后,簇合物KRuCo_3(CO)_(12)中的RuCo_3簇骨架与担体表面原子发生强相互作用.在反应温度下,可形成高分散型催化剂.认为CO加氢反应是按碳烯机理进行.

关 键 词:Ru-Co羰基簇,负载型催化剂,电子能谱,程序升温

Abstract:upported Ru-Co carbonyl cluster catalyst is prepared.The characterization of surface chem-istry and the desorption products of supported bimetallic cluster catalyst under different atmo-spheres are studied by means of X-ray photoelectron spectroscopy(XPS)and temperature pro-grammed desorption(TPD).The results show that there is a strong interaction between the clus-ter metal framework(RuCo_3)and the surface atom of supporter.It is suggested that the CO hy-drogenation is carried out by the carbene mechanism.
Keywords:Ru-Co carbonyl cluster supported bimetallic catalyst XPS TPD
