Single‐atom catalysts (SACs) have rapidly become a hot topic in photocatalytic research due to their unique physical and chemical properties, high activity, and high selectivity. Among many semiconductor carriers, the special structure of carbon nitride (C3N4) perfectly meets the substrate requirements for stabilizing SACs; they can also compensate for the photocatalytic defects of C3N4 materials by modifying energy bands and electronic structures. Therefore, developing advanced C3N4‐based SACs is of great significance. In this review, we focus on elucidating efficient preparation strategies and the burgeoning photocatalytic applications of C3N4‐based SACs. We also outline prospective strategies for enhancing the performance of SACs and C3N4‐based SACs in the future. A comprehensive array of methodologies is presented for identifying and characterizing C3N4‐based SACs. This includes an exploration of potential atomic catalytic mechanisms through the simulation and regulation of atomic catalytic behaviors and the synergistic effects of single or multiple sites. Subsequently, a forward‐looking perspective is adopted to contemplate the future prospects and challenges associated with C3N4‐based SACs. This encompasses considerations, such as atomic loading, regulatory design, and the integration of machine learning techniques. It is anticipated that this review will stimulate novel insights into the synthesis of high‐load and durable SACs, thereby providing theoretical groundwork for scalable and controllable applications in the field.

The main challenges faced by lithium sulfur (Li−S) batteries are severe shuttle reactions and the promotion of delayed reaction kinetics within the battery. To address these issues, this study synthesized an alloy material (CoNi). This material has excellent and abundant polysulfide adsorption active sites, thereby improving the reaction kinetics inside the battery. It is worth noting that the unique properties of metal atoms are conducive to suppressing the shuttle effect. Without adding a carbon substrate and using only the CoNi alloy as the separator coating layer, the battery can achieve excellent performance. The battery modified with a CoNi separator exhibited an initial discharge capacity of up to 935 mAh g −1 in a long 1 C cycle, with small attenuation (0.058%) single cycle after 1000 cycles. Even at a high rate of 2 C, it can remain stable for 350 cycles, with an initial discharge capacity of 821 mAh g −1 and a single cycle attenuation of 0.098%. Under a high sulfur load (3.65 mg cm −2 ) and a current density of 0.1 C, the initial capacity is 1064 mAh g −1 , and the battery remains stable over 30 cycles. In addition, this study directly demonstrated the significant catalytic effect of CoNi material on the internal reactions of batteries through Li 2 S nucleation experiments, thereby improving the reaction kinetics. This study provides a new method for promoting the practical application of Li−S batteries and narrows the gap between theoretical and experimental results through long cycles and high sulfur loads.
