合成了一种新型的HPW/S iO2复合介孔材料,通过XRD,TEM,UV-V is和FT IR等表征证明,HPW均匀且稳定地包藏到介孔材料由S iO2网络组成的孔壁之中.催化结果表明,其在大分子催化反应中有较高的活性,在酯化反应中连续循环使用未发现活性组分流失,表明其在多相催化和大分子催化反应中有较好的工业应用前景. A new type of HPW / SiO 2 composite mesoporous materials was synthesized and characterized by XRD, TEM, UV-V is and FT IR. The results showed that HPW was uniformly and stably enveloped in the pore walls of mesoporous materials composed of SiO 2 networks In the catalytic results show that it has a high catalytic activity in the macromolecule in the esterification reaction was not found in the continuous circulation of the loss of the active ingredient, indicating that it is better in heterogeneous catalysis and catalytic reaction of macromolecules Industrial application prospects.
