Abstract

Fundamental insights into electrode–electrolyte interfaces are crucial for our understanding of electrochemical processes. Standard electrochemical methods, such as cyclic voltammetry, can reveal important information about the systems of interest. Nevertheless, information about structure and morphology of the electrode–electrolyte interface is not that easily accessible. In situ scanning tunnelling microscopy can resolve the electrode as well as the direct interface to the electrolyte in real time during electrochemical measurements. This includes changes of the electrode in the nanometre to micrometre range, for example, during metal deposition or corrosion, as well as the observation of ordered molecular adlayers on the electrode. In this work, we want to highlight the capabilities of such studies to better understand the fundamental processes of electrocatalysis and metal deposition and dissolution, which are essential to electrochemical energy storage systems.

通过原位扫描隧道显微镜深入了解电极-电解质界面
从根本上了解电极-电解质界面对我们理解电化学过程至关重要。循环伏安法等标准电化学方法可以揭示有关系统的重要信息。然而,有关电极-电解质界面结构和形态的信息却不那么容易获得。原位扫描隧道显微镜可以在电化学测量过程中实时解析电极以及与电解质的直接界面。这包括电极在纳米到微米范围内的变化,例如在金属沉积或腐蚀过程中的变化,以及对电极上有序分子吸附层的观察。在这项工作中,我们希望强调此类研究的能力,以便更好地理解电催化和金属沉积与溶解的基本过程,这对电化学储能系统至关重要。

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 •
