Abstract

Porous silica was first synthesized using sodium silicate as silicon source. Ionic liquid-polymer functionalized porous silica was prepared via the chain transfer polymerization of grafting an ionic liquid monomer, 1-allyl-3-methylimidazolium bromide, onto the surface of the silica . The resultants were characterized by scanning electron microscope, nitrogen physisorption experiment, thermogravimetric analysis, Fourier transform infrared spectra and so on. The novel hybrid material loaded with Pd can be used as a catalyst. The experimental results indicate that the catalyst has a prominent effect on the degradation of methyl orange in the presence of hydrogen peroxide. The reasonable explanation is that the metal component of the catalyst stimulated the dissociation of hydrogen peroxide to release abundant highly active free radicals which can rapidly ruin the structure of methyl orange molecules in water. Finally, a probable catalytic mechanism based on diffusion was proposed.
