| Abstract: | Pt nano - cluster/chitosan hybrid membrane （Pt/CS） was prepared and its catalytic activity for the partial hydrogenation of benzene was investigated. The structure of the catalysts was characterized by TEM, FT-IR, XRD and XPS. TEM and XPS results indicated that the average diameter of Pt particles was 3.7 nm and Pt was coordinated with N and O in chitosan hybrid membrane （CS） to some extent. The experimental results showed that Pt/CS catalyst exhibited high selectivity to Cyclohexene of 68% in liquid-phase benzene hydrogenation for 2 h ;there was no cyclohexene in the product using Pt nano-particles as the catalyst without chitosan membrane and the only product was cyclohexane. |
