Contact electrification (CE) is a common physical process by which triboelectric charges are generated through the mutual contact between two objects. Despite the ongoing debates on CE's mechanism, recent advancements in technology have elucidated the primary role of electron transfer in most CE processes. This discovery leads to the spawning of an emerging field, known as contact-electro-catalysis (CEC), which utilizes the electron transfer phenomenon during CE to initiate CEC. In this work, we provide the first comprehensive review of the recent progress of the solid-liquid interface-mediated CEC process, including its working principles, relationship with surface science, recent breakthroughs in applications, and future challenges. We aim to provide fundamental guidance for researchers to understand the reaction mechanism of the CEC process and to propose potential pathways to enhance CEC efficiency from a surface and interfacial science perspective. Later, recent application scenarios using the novel CEC techniques are summarized, including wastewater treatment, efficient generation of hydrogen peroxide (HO), lithium-ion battery recycling, and CO reduction. In general, CEC technology has opened a new avenue for catalysis, effectively expanding the range of catalyst options and holding promise as a solution to a variety of complex catalytic challenges in the future.
接触起电（CE）是一种常见的物理过程，通过两个物体之间的相互接触产生摩擦电荷。尽管关于CE机制的争论仍在继续，但最近的技术进步已经阐明了电子转移在大多数CE过程中的主要作用。这一发现催生了一个新兴领域，即接触电催化（CEC），它利用CE过程中的电子转移现象来引发CEC。在这项工作中，我们首次全面综述了固液界面介导的CEC过程的最新进展，包括其工作原理、与表面科学的关系、应用方面的最新突破以及未来的挑战。我们旨在为研究人员提供基础指导，以了解CEC过程的反应机制，并从表面和界面科学的角度提出提高CEC效率的潜在途径。随后，总结了使用新型CEC技术的近期应用场景，包括废水处理、高效生成过氧化氢（HO）、锂离子电池回收以及CO还原。总的来说，CEC技术为催化开辟了一条新途径，有效地扩大了催化剂的选择范围，并有望在未来解决各种复杂的催化挑战。
