Abstract

Abstract:

After silane coupling agent 4-(chloromethyl)phenyltrichlorosilicane was grafted onto silica particles, the silica particles were endowed with hydrophobic benzyl choloride groups. Amphiphilic colloidal particles with ionic liquid groups were obtained by reacting with dodecyl imidazole. Pt nanoparticles were loaded onto the surface of amphiphilic colloidal particles by adsorption of chloroplatinic acid and further reduction by sodium borohydride. Scanning electron microscope(SEM), transmission electron microscope(TEM), X-ray diffractometer(XRD) and Fourier transform infrared spectroscopy(FTIR) were used to characterize the samples structures. The oxidation reaction of benzyl alcohol was used to evaluate the catalytic performance of amphiphilic colloidal particles loaded with Pt particles. The result indicates that the yield of benzoic acid is up to 90%.
