The ultimate goal of heterogeneous catalysis is to precisely regulate chemical reaction transformations. Zeolite catalysts, with their unique shape-selective properties, have been widely used in chemical production, however, achieving highly efficient catalytic reactions requires accurate control over the structure of active sites to minimize side reactions. Since aluminum (Al) atoms located at crystallographically nonequivalent T-sites form the active centers of zeolites, controlling the distribution of Al at both local (T-site level) and spatial (regional) scales has become a research focus in zeolite science. This review systematically summarizes strategies for regulating Al distribution in zeolites—both bottom-up and top-down approaches—as well as advanced characterization techniques. In the bottom-up strategy, using representative zeolite frameworks as examples, we elucidate the mechanism by which organic and inorganic structure-directing agents influence Al distribution. Combined with theoretical calculations, we reveal how van der Waals forces, electrostatic interactions, and hydrogen bonding govern the spatial positioning of Al. In the top-down strategy, selective removal or incorporation of Al atoms is achieved based on variations in the stability of heteroatoms (or Al atoms) at different T-sites, and the advantages and limitations of this method are critically discussed. Accurate characterization of Al distribution is essential for evaluating the effectiveness of regulation strategies; thus, recent advances in Al site characterization are reviewed, emphasizing that multi-technique approaches can yield more reliable structural information. Finally, the review summarizes the merits and drawbacks of each strategy and envisions the future integration of artificial intelligence and big-data-driven high-throughput microchannel zeolite synthesis to realize precise control of Al distribution. The fusion of multiple characterization techniques is further expected to enable accurate structural elucidation, ultimately guiding the rational design of reaction-specific, high-performance zeolite catalysts.
