Electrochemical conversion of abundant resources, such as carbon dioxide, water, nitrogen, and nitrate, is a remarkable strategy for replacing fossil fuel-based processes and achieving a sustainable energy future. Designing an efficient and selective electrocatalysis system for electrochemical conversion reactions remains a challenge due to a lack of understanding of the reaction mechanism. Shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS) is a promising strategy for experimentally unraveling a reaction pathway and rate-limiting step by detecting intermediate species and catalytically active sites that occur during the reaction regardless of substrate. In this review, we introduce the SHINERS principle and its historical developments. Furthermore, we discuss recent SHINERS applications and developments for investigating intermediate species involved in a variety of electrocatalytic reactions.
将二氧化碳、水、氮和硝酸盐等丰富资源进行电化学转化，是取代基于化石燃料的工艺并实现可持续能源未来的一项卓越策略。由于对反应机理缺乏了解，设计用于电化学转化反应的高效且选择性的电催化系统仍然是一项挑战。壳层隔离纳米粒子增强拉曼光谱（SHINERS）是一种很有前景的策略，可通过检测反应过程中出现的中间物种和催化活性位点来实验性地揭示反应途径和限速步骤，而无需考虑底物。在这篇综述中，我们介绍了SHINERS原理及其历史发展。此外，我们还讨论了SHINERS在研究各种电催化反应中涉及的中间物种方面的最新应用和进展。
