All electrochemical and electrocatalytic processes occur at the boundary between an electrode and an electrolyte. Progress in the field of electrochemistry requires a detailed microscopic understanding of these complex solid-liquid interfaces, making this a captivating field for in situ surface-sensitive microscopic techniques, such as scanning probe microscopy. In this Perspective, we outline the roadmap of electrochemical scanning probe microscopy and explore its most recent developments in fundamental research on interface characterization and electrocatalysis. Most importantly, we introduce the reader to the simultaneous operation of electrochemical scanning tunneling microscopy and force microscopy using a qPlus sensor, highlighting its potential to provide high precision, enhanced flexibility and versatility, particularly as a combined approach to interface characterization. Additionally, we identify key future opportunities and challenges.
所有的电化学和电催化过程都发生在电极与电解质之间的界面处。电化学领域的进展需要对这些复杂的固液界面有详细的微观理解，这使得该领域成为原位表面敏感微观技术（如扫描探针显微镜）的一个引人入胜的领域。在这篇展望文章中，我们概述了电化学扫描探针显微镜的发展历程，并探讨了其在界面表征和电催化基础研究方面的最新进展。最重要的是，我们向读者介绍了使用qPlus传感器同时操作电化学扫描隧道显微镜和力显微镜，强调了其提供高精度、增强的灵活性和多功能性的潜力，特别是作为一种用于界面表征的组合方法。此外，我们还确定了未来的关键机遇和挑战。
