The Zr-SBA-15 catalysts with different Zr/Si ratio were prepared by one pot method using te-traethoxysilane and zirconium dinitrate oxide as precursors. The effects of Zr/Si ratio on the structure, tex-ture, surface acidity and catalytic performance of Zr-SBA-15 catalysts for the (Meerwein-Ponndorf-Verley) MPV transfer hydrogenation of cinnamaldehyde were investigated, by means of N2 physical adsorption, X-ray powder diffraction, NH3 temperature-programmed desorption and pyridine in situ infrared. The re-sults show that the prepared Zr-SBA-15 catalysts exhibited regular hexagonal mesoporous structure with L acid as the main surface acid center. With the increase of Zr/Si mole ratio, the most probable pore size of Zr-SBA-15 catalyst decreased gradually, the amount of L acid increased continuously, and the amount of B acid changed lightly. The cinnamaldehyde conversion increased first and then tended to be stable. The selectivity of the target product cinnamol increased, while selectivity of the by-product 1- benzene propyl-ene-2-propyl ether decreased. When the Zr/Si mole ratio was 0.1, the Zr-SBA-15 catalyst showed the op-timal catalytic performance: the conversion of cinnamaldehyde reached 96.2%, and the selectivity of cin-namyl alcohol was 95.2%. The conversion of cinnamaldehyde kept over 90%, and the selectivity of cin-namyl alcohol was above 95% after 8 times cycle application experiment.
