苯分子在过渡金属表面上的吸附与烃类转化、多相催化以及表面理论有极密切的关系。实验测得苯在Ni、Pd、Pt表面上的吸附基本上不发生畸变。苯环骨架平行于金属表面,以π键同金属表面进行键合。Hofmann等用角分辨光电子谱研究了苯在Pd(100)面上的结构和取向,得出在室温下苯吸附在Pd(100)面上呈(2×2)R45的
The adsorption of benzene on the transition metal surface is closely related to hydrocarbon conversion, heterogeneous catalysis and surface theory. It is experimentally found that the adsorption of benzene on the surface of Ni, Pd and Pt is basically not distorted. The benzene ring skeleton is parallel to the metal surface and bonds to the metal surface by π bond. Hofmann et al. Studied the structure and orientation of benzene on the Pd (100) surface by angle-resolved photoelectron spectroscopy. The results showed that benzene adsorbed on Pd (100) surface at room temperature was (2 × 2) R45
