Single‐atom metals (SAMs), despite being promising for high‐utilization catalysis, biomedicine, and energy storage, usually suffer from limited catalytic performance caused by low metal loading. Herein, via an oriented diffusion strategy, all‐region ultrahigh‐loading (18.9 wt.%) Sn‐SAMs over carbon nanorings matrix (Sn‐SAMs@CNR) are initially achieved based on the transformation of a g‐C3N4@SnO2@polydopamine ring‐like nested structure. The formation process of Sn‐SAMs involves a critical conversion from oxygen‐coordination (SnO2) to nitrogen‐coordination (Sn‐N4) and simultaneous anti‐Osterwalder ripening promoted under spatial confinement. Notably, the g‐C3N4‐derived N‐containing gaseous intermediates dynamically drive the oriented diffusion (inside‐out diffusion) of Sn‐SAMs across the carbon nanorings, realizing an all‐region ultrahigh loading of SAMs throughout the carbon matrix. This strategy is also applied to other metal materials (Fe, Co, Ni, Cu, and Sb), and features excellent universality. When applied as the anode for sodium‐ion batteries, experimental analyses and theoretical calculations demonstrate that high‐loading Sn‐N4 active sites significantly optimize electron density distribution and improve reaction kinetics. Consequently, Sn‐SAMs@CNR exhibits outstanding durability of 364 mAh g−1 even after 5000 cycles with an impressively low (0.00068%) capacity decay per cycle. This work opens up a universally new avenue for all‐region ultrahigh loading of SAMs to carbon matrix for high‐performance energy storage.

Single‐atom catalysts (SACs) demonstrate high selectivity, maximal atom utilization, and unique active site configurations, establishing them as a rapidly expanding research field. Understanding the intrinsic relationship between structure and catalytic performance is crucial for the effective use of SACs in catalysis. However, providing a clear explanation of the coordination environment and intrinsic structural regulation of SACs remains a significant challenge for next‐generation renewable energy materials, especially in advanced oxidation and reduction processes critical for sustainable energy applications. This comprehensive review offers an in‐depth overview of the current progress and design of SACs, with a specific focus on precise synthesis, structural control, and the relationship between structure and performance. Furthermore, we elucidate the reaction mechanisms of various catalytic systems and the selective methods used to precisely synthesize and enhance catalytic reactions in the sustainable energy sector. Finally, this review explores the complex challenges in investigating and developing SACs and offers a perspective on solutions in advanced oxidation and reduction technologies for future research to overcome these challenges and achieve practical applications.
