摘　　要：综述了介孔氧化铝及其前体的晶体结构与表面化学的研究进展。从介孔氧化铝的主要合成路线出发,对介孔氧化铝的控制合成进行了系统总结。并对近几年合成的新型氧化铝(包括规整孔道介孔氧化铝、不同形貌氧化铝、纳米晶氧化铝组装体等)进行了详细介绍。重点介绍了介孔氧化铝及其前体的晶体生长及控制策略、铝的微环境和表面羟基结构等方面的研究。对该领域的热点问题和存在的研究机遇进行了展望,提出要加强对氧化铝的介观层面的研究。Research progresses in crystal structure and surface chemistry of mesoporous alumina and its precursor were reviewed. Starting from the main synthetic routes of mesoporous alumina, its controlled synthesis was systemically summarized. In addition, new varieties of mesoporous alumina with ordered pores different morphologies and nano-crystalline alumina assemblies were introduced in detail. The crystal growth and control strategies, and the surface aluminum micro-environment and the surface hydroxyl groups were discussed in detail. Hot issues and research opportunities in this field were prospected, and the suggestion of strengthening research in the alumina meso-level was proposed.
