Опубликована: Март 6, 2024

Abstract Tailoring advanced anisotropy‐driven efficient separation and migration of photogenerated carriers is a pivotal stride toward enhancing photocatalytic activity. Here, CdS‐MoS 2 binary photocatalysts are tailored into dumbbell shape by leveraging the rod‐shaped morphology CdS employing an in situ tip‐induction strategy. To further enhance activity, photo‐deposition strategy incorporated to cultivate MnO x particles on dumbbell‐shaped . The deposition effectively isolated oxidatively active sites surface, emphasizing reductively crystalline face CdS, specifically (002) face. Benefiting from its robust activity as reduction site, MoS adeptly captures electrons, facilitating H + produce hydrogen. anisotropically driven markedly mitigates Coulomb force or binding thus promoting smoother site for hydrogen evolution. evolution rate 35MnO ‐CdS‐MoS ‐3 surpasses that nearly order magnitude, achieving quantum efficiency 22.30% at 450 nm. Under simulated solar irradiation, it attains 42.86 mmol g −1 h This work imparts valuable insights design dual co‐catalysts, spatial vectorial charge migration, analysis pathways carriers.

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.
