摘要:

介孔氧化鋁材料自合成以來，因其在催化、吸附等領域的廣泛應用受到了極大的關注。隨著石油化工領域大分子反應不斷增加，介孔氧化鋁的使用逐漸受到限制，合成具有分級結構介孔-大孔氧化鋁材料將具有重大意義。分級結構介孔-大孔氧化鋁因其同時具有介孔和大孔孔道，不僅促進了客體分子在孔道內部的傳送、減小擴散阻力，而且增大了孔道的比表面積，有助于改善吸附和分離效率、延長催化壽命，因此在吸附和催化方面具有廣泛的應用前景。介紹了采用單模板法、雙模板法和無模板法合成分級結構介孔-大孔氧化鋁材料，并對材料在吸附和催化領域的應用進行探討，最后對分級結構介孔-大孔氧化鋁材料的發展趨勢進行了展望。

Abstract:

From the first preparation of mesoporou alumina, more and more attentions have been paid to the material for its wide applications in catalysis and adsorption. With the development of macromolecule reaction in petrochemical industry, the use of mesoporous alumina has been gradually limited, so the preparation of hierarchically meso-marcoporous alumina will have great significance. The hierarchically meso-macroporous alumina with mesopores and macropores simultaneously has many potential applications in adsorption and catalytic fields，because the meso-macroporous structure is not only benefical to the transmission of guest molecule in channel, but also good for the improvement of specific surface area, then the efficiency of adsorption and separation can be promoted and the catalyst lifetime can also be extended. The review introduces the preparation methods of meso-macroporous alumina by single template, dual template and free template, as well as the practical applications in adsorption and catalytic fields. Finally, the development trend of hierarchically meso-macroporous alumina is also discussed.
