【摘要】：介孔氧化铝材料自合成以来,因其在催化、吸附等领域的广泛应用受到了极大的关注。随着石油化工领域大分子反应不断增加,介孔氧化铝的使用逐渐受到限制,合成具有分级结构介孔-大孔氧化铝材料将具有重大意义。分级结构介孔-大孔氧化铝因其同时具有介孔和大孔孔道,不仅促进了客体分子在孔道内部的传送、减小扩散阻力,而且增大了孔道的比表面积,有助于改善吸附和分离效率、延长催化寿命,因此在吸附和催化方面具有广泛的应用前景。介绍了采用单模板法、双模板法和无模板法合成分级结构介孔-大孔氧化铝材料,并对材料在吸附和催化领域的应用进行探讨,最后对分级结构介孔-大孔氧化铝材料的发展趋势进行了展望。
[Abstract]:Since its synthesis, mesoporous alumina materials have been widely used in catalysis, adsorption and other fields. With the increasing of macromolecular reactions in petrochemical industry, the use of mesoporous alumina has been gradually restricted. It will be of great significance to synthesize mesoporous and macroporous alumina materials with hierarchical structure. Because of the mesoporous and macroporous alumina with graded structure, it not only promotes the transport of guest molecules in the pore channel, but also reduces the diffusion resistance. It also increases the specific surface area of the pore, improves the efficiency of adsorption and separation, prolongs the catalytic life, so it has a wide application prospect in adsorption and catalysis. The mesoporous and macroporous alumina materials with graded structure were synthesized by double template method and no template method. The applications of the materials in adsorption and catalysis were discussed. Finally, the development trend of mesoporous alumina materials with graded structure was prospected.
