Mesoporous silica of SBA-15 type was modified for the first time with 3-(trihydroxysiyl)-1-propanesulfonic acid (TPS) by post-synthesis modification involving microwave or conventional heating in order to generate the Brønsted acidic centers on the material surface. The samples structure and composition were examined by low temperature N₂ adsorption/desorption, XRD, HRTEM, elemental and thermal analyses. The surface properties were evaluated by esterification of acetic acid with n-hexanol used as the test reaction. A much higher efficiency of TPS species incorporation was reached with the application of microwave radiation for 1 h than conventional modification for 24 h. It was found that the structure of mesoporous support was preserved after modification using both methods applied in this study. Materials obtained with the use of microwave radiation showed a superior catalytic activity and high stability.

SBA-15类型的中孔二氧化硅首次通过3-（三羟基甲硅烷基）-1-丙烷磺酸（TPS）进行了合成后修饰，涉及微波或常规加热，目的是在材料表面产生布朗斯台德酸性中心。通过低温N ₂检查样品的结构和组成吸附/解吸，XRD，HRTEM，元素和热分析。通过用乙酸与正己醇酯化作为测试反应来评估表面性质。微波辐射1 h比传统改性24 h的TPS物种掺入效率高得多。发现使用本研究中应用的两种方法对介孔支持物的结构进行修饰后均得以保留。使用微波辐射获得的材料显示出优异的催化活性和高稳定性。
