These structures offer immense potential for enhancing light harvesting and tuning the localized surface plasmon resonance (LSPR). However, the lack of a universal and scalable synthetic method for constructing diverse semiconductor shells remains a major challenge. In this study, we report for the first time a versatile low-temperature two-step method for fabricating hollow gold nanoparticles (HGNs)@semiconductor core–shell heterostructures. By employing mercaptobenzoic acid (MBA) as a linker molecule and polyvinylpyrrolidone (PVP) as a stabilizing agent, this method enables the uniform deposition of various semiconductors, including CuO, Fe₃O₄, CdS, FeS, and Ni(OH)₂. The method exhibits broad material applicability and allows precise control of LSPR by adjusting the semiconductor shell thickness, spanning a spectral range from the visible to the near-infrared (NIR) region. Our work not only demonstrates the modulation of LSPR properties through shell thickness but also provides new insights into the metal–semiconductor interfacial dynamics and plasmonic energy transfer mechanisms. This versatile synthetic platform not only lays the foundation for next-generation photocatalysts and optoelectronic devices in the visible and NIR regions but also broadens its potential applications to other metal@compound core–shell systems across fields, such as optoelectronics, energy, and catalysis.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"67 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143545898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, a multitude of researchers have uncovered a range of novel SMSI types and induction methods including oxidized SMSI (O-SMSI), adsorbent-mediated SMSI (A-SMSI), and wet chemically induced SMSI (Wc-SMSI). Consequently, a systematic and critical review is highly desirable to illuminate the latest advancements in SMSI and to deliberate its application within heterogeneous catalysts. This article provides a review of the characteristics of various SMSI types and the most recent induction methods. It is concluded that SMSI significantly contributes to enhancing catalyst stability, altering reaction selectivity, and increasing catalytic activity. Furthermore, this paper offers a comprehensive review of the extensive application of SMSI in the electrocatalysis of hydrogen evolution reaction (HER), oxygen evolution reaction (OER), oxygen reduction reaction (ORR), and carbon dioxide reduction reaction (CO₂RR).

Herein, we constructed Z-scheme ZnIn₂S₄/UiO66-NH₂ (ZIS/UNH) heterojunctions, integrating the ORR and WOR dual pathways for photocatalytic H₂O₂ generation without noble cocatalysts and sacrificial agents. The optimized ZIS/UNH exhibits the highest H₂O₂ yield of 0.85 mmol g^–1 h^–1, which is 2.2 and 14 times those of ZIS and UNH, respectively. The formation of the Z-scheme heterojunction efficiently promotes the separation and transfer of photogenerated carriers while retaining holes with high oxidizing ability and electrons with strong reducing ability. The free radical quenching and DMPO-ESR radical trapping experiments demonstrate that the ZIS/UNH heterojunctions produce H₂O₂ in a dual-channel mode different from the single-channel ZIS.
