摘要

在这一见解中，我们强调了ZnO/CuInS2 S-scheme异质结上等离子体响应的出现，这是孟等人最近报道的（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粒子或缺陷纳米晶体中得到广泛认可。在他们的工作中，孟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。利用SPR效应，制备的ZnO/CuInS2光催化剂在近红外（NIR）光催化下对H2O2的生成表现出优异的光催化活性。这种异质结诱导的等离子体响应主要集中在红外区，从而将光催化活性扩展到可见光之外，为促进异质结在人工光合作用中的发展开辟了新的途径。

S-scheme heterojunction-induced surface plasmon response

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.
