摘要

开发高效电催化剂需要深入了解其结构与活性之间的关系。扫描电化学显微镜（SECM）和扫描电化学电池显微镜（SECCM）是绘制表面活性位点图和研究原位甚至操作纳米级异相电催化过程的强大技术，因此在研究电催化机理方面发挥着举足轻重的作用。在本综述中，我们将介绍 SECM 和 SECCM 的基本原理以及最常用操作模式的原理。本综述介绍了自 2021 年以来在 SECM 和 SECCM 方面所做的工作，并特别强调了新兴的电催化应用和值得注意的趋势。

Recent advances in scanning electrochemical microscopy and scanning electrochemical cell microscopy for electrocatalytic applications

The development of highly efficient electrocatalysts requires a deeper understanding of their structure–activity relationship. Scanning electrochemical microscope (SECM) and scanning electrochemical cell microscope (SECCM) are powerful techniques for mapping surface activity site and investigating heterogeneous electrocatalytic processes down to the nanoscale in situ and even operando, thus playing a pivotal role in studying electrocatalytic mechanism. In this review, we introduce the fundamentals of SECM and SECCM, and the principles of the most frequently used operational modes. This review describes work done in SECM and SECCM since 2021 with a particular emphasis on emerging electrocatalytic applications and noteworthy trends.

期刊介绍： The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner: 1.The views of experts on current advances in electrochemistry in a clear and readable form. 2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications. In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle: • Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
