摘要：Pt supported on mesoporous silica SBA-15 materials with various loadings are controllably synthesized by metal-organic(MO) CVD of Pt(C5H9)(2) in a Y-tube reactor. The precursor, Pt(C5H9)(2), is successfully prepared by the reaction of dichloro(1,5-cyclooctadiene)platinum ((COD)PtCl2) with pent-4-en-1-ylmagnesium bromide, which is confirmed by proton nuclear magnetic resonance (H-1-NMR). Transmission electron microscopy (TEM) images show that Pt nanoparticles with an average size of 4.6 +/- 1.1 nm are dispersed uniformly onto the SBA-15. The performance of Pt/SBA-15 for the hydrogenation of o-chloronitrobenzene (o-CNB) is tested, and is able to achieve high catalytic activity (97%) and selectivity (72%).
