Single‐atom catalysts (SACs) are attracting extensive attention due to their incredibly catalytic activity and selectivity, high utilization of metal atoms, and obvious cost reduction. The unique ordered porous materials (OPMs) are promising carriers for stabilizing single atoms due to their large surface areas and uniformly tunable pore sizes. Meantime, the geometric and electronic structures of single‐atom metals can be tuned by the interaction between the single‐atoms (SAs) and OPMs to enhance the catalytic activity of SACs. The SACs based on OPMs, such as zeolites, metal–organic frameworks, and ordered mesoporous materials, have been developing fast recently. Herein, we review recent advancements on structural feature, synthetic strategy, characterization technique, and catalytic applications of OPMs‐based SACs. The opportunities and challenges about SAs/OPMs are also provided to develop the novel catalysts with superior catalytic performances in the future. Ordered porous materials (OPMs)‐based single‐atom catalysts (SACs) with unique electronic state via a confinement effect have aroused extensive interest due to their large surface areas and uniformly tunable pore sizes. This review summarizes the recent development of OPMs‐based SACs in structures, synthetic methods, characterization technologies, and catalytic applications.
