摘要	Propylsulfonic acid and methyl bifunctionalized TiSBA-15 silica material, TiSBA-15-Me-PrSO3H, is prepared by a direct nonionic surfactant-templated sol-gel co-condensation approach combined with low-temperature hydrothermal treatment. The structural integrity of the incorporated propylsulfonic acid groups and terminally bonding methyl groups are studied by C-13 CP-MAS NMR and Si-29 MAS NMR spectroscopy, while the chemical state of Ti(IV) species in the hybrid material is tested by XPS and UV-Vis/DRS. The ordered mesostructure, morphology and porosity of as-prepared hybrid material are characterized by low-angle XRD measurements, TEM observations and nitrogen gas porosimetry measurements. As the efficient solid acid catalyst, the heterogeneous acid catalytic activity and stability of the TiSBA-15-Me-PrSO3H are evaluated by esterification of palmitic acid and transesterification of yellow horn oil with methanol under refluxing temperature (65 degrees C) and atmospheric pressure. Based on the physicochemical properties and catalytic testing results, the excellent heterogeneous acid catalytic behaviors of as-prepared hybrid catalyst are explained by the contribution of their strong Bronsted and Lewis acidity, excellent porosity properties as well as surface hydrophobicity.
