In this insight, we highlighted the emergence of a plasmonic response over ZnO/CuInS₂ S-scheme heterojunction, which has been recently reported by Meng et al. (Adv. Mater. 2024, 36, 2406460). The surface plasmon resonance (SPR) effect is widely acknowledged in plasmonic metal nanoparticles or defective nanocrystals. In their work, Meng et al. proposed another approach to generate a plasmonic response in S-scheme heterojunction photocatalysts. By virtue of the SPR effect, the obtained ZnO/CuInS₂ photocatalyst exhibited supreme photocatalytic activity for H₂O₂ production under near-infrared (NIR) light. This heterojunction-induced plasmonic response is mainly concentrated in the IR regime thus extending the photocatalytic activity beyond the visible light limit and opening new avenues for boosting the development of heterojunctions in artificial photosynthesis.

S 型异质结诱导的表面等离子体响应


在这一见解中，我们强调了 ZnO/CuInS₂ S 型异质结上出现的等离子体响应，Meng 等人最近报道了这一点 （Adv. Mater. 2024， 36， 2406460）。表面等离子体共振 （SPR） 效应在等离子体金属纳米颗粒或有缺陷的纳米晶体中得到广泛认可。在他们的工作中，Meng 等人提出了另一种在 S 型异质结光催化剂中产生等离子体响应的方法。凭借 SPR 效应，所获得的 ZnO/CuInS₂ 光催化剂在近红外 （NIR） 光下表现出对 H₂O₂ 产生极高的光催化活性。这种异质结诱导的等离激元响应主要集中在红外状态下，从而将光催化活性扩展到可见光极限之外，并为促进人工光合作用中异质结的发展开辟了新的途径。
