An Efficient Route to Highly Organized, Tunable Macroporous-Mesoporous Alumina

摘要

The preparation of bimodal porous matenals incorporating two distinct pore networks spanning different scales is an important challenge for chemical applications including catalysis, sorption, and separation science. Since the parallel development of mesos-tructuring and macrostructuring routes in the 1990s, the synthesis of hierarchical macroporous-mesoporous oxides has become an exciting area of materials chemistry. The first report of ordered macroporous-mesoporous silica was followed by the discovery of numerous structuring agents able to direct macropore formation.
