摘　　要：电催化在能源转化与存储方面有着广阔的应用前景,并已成为当今世界的研究热点.对于大多数电催化体系而言,其催化性能的优化与提升,都需倚赖活性中心的合理构建以及催化机制的精确描述.为此,测试手段的不断丰富可以极大促进电催化的深入研究与应用.近年来,微纳(器件)加工技术的不断成熟和跨学科发展为电催化材料和过程的研究提供了更精细的全新平台.本文针对电催化研究的不同方向,从结构表征与精准测量、场效应调控和电输运关联动力学三个方面总结了近年来微纳器件技术在电催化领域中的研究进展.最后,本文展望了微纳器件技术在电催化领域所面临的挑战及应用前景.Electrocatalysis has broad application prospects in the energy conversion and storage, and thus has gradually become a research hotspot over the world. For most electrocatalytic systems, the optimization and improvement of their electrocatalytic performances are usually generated from the reasonable construction of active sites and accurate descriptions of the catalytic mechanism. The continuous enrichment of measurement methodologies can greatly promote the in-depth studies and applications of electrocatalysis. In recent years, the continuous maturity and cross-disciplinary developments of micro-nano(device) processing technologies have provided a new and more sophisticated platform(s)for the study of electrocatalytic materials and processes. Here, aiming at the different directions of electrocatalysis research, this review summarizes the latest progress of micro-nano device technologies in electrocatalysis-related research fields from three perspectives: structure characterizations and accurate measurements, electric field effect regulations and electric transport correlated dynamics. Finally, the application prospects and challenges of micro-nano device technologies in the field of electrocatalysis are prospected.
