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.
