SusMat, Год журнала: 2024, Номер 4(5)

Опубликована: Июль 18, 2024

Abstract Single‐atom catalysts (SACs) have rapidly become a hot topic in photocatalytic research due to their unique physical and chemical properties, high activity, selectivity. Among many semiconductor carriers, the special structure of carbon nitride (C 3 N 4 ) perfectly meets substrate requirements for stabilizing SACs; they can also compensate defects C materials by modifying energy bands electronic structures. Therefore, developing advanced ‐based SACs is great significance. In this review, we focus on elucidating efficient preparation strategies burgeoning applications SACs. We outline prospective enhancing performance future. A comprehensive array methodologies presented identifying characterizing This includes an exploration potential atomic catalytic mechanisms through simulation regulation behaviors synergistic effects single or multiple sites. Subsequently, forward‐looking perspective adopted contemplate future prospects challenges associated with encompasses considerations, such as loading, regulatory design, integration machine learning techniques. It anticipated that review will stimulate novel insights into synthesis high‐load durable SACs, thereby providing theoretical groundwork scalable controllable field.
