Unlocking emerging catalytic applications of single-entity collision electrochemistry

Establishing the link between catalytic activity and the structure of individual entities in an ensemble system can be challenging, as the presented data are often averaged in bulk system. Single-entity collision electrochemistry (SECE) stands out as a powerful tool for investigating the intrinsic catalytic activities of single entities with high sensitivity, high throughput, and fast response. Recent advancements in SECE technology have demonstrated significant potential in various emerging applications, particularly in the rapid screening of catalysts and supports, in situ identification of catalytic activity and assembly structure, and real-time monitoring of dynamic catalytic behaviors. This review summarizes the recent research results, pioneering studies, and future trends in this field. It also discusses the challenges faced by SECE in exploring new application scenarios.
