Abstract

Covalent organic frameworks (COFs) represent an emerging class of crystalline porous polymers with high porosity, good stability, and adjustable structure, and their excellent characteristics lay a solid foundation for electrocatalysis. This review systematically introduces the design principles of the catalytic sites in two-dimensional (2D) COF-based electrocatalysts and analyzes the relationship between 2D COF structure and their electrocatalytic performances. In particular, the recent progress in the field of 2D COFs as electrocatalysts is comprehensively summarized. Finally, we discuss the current shortcomings and challenges on tailoring 2D COF for high-performance electrocatalysts in details, and look forward to promoting more researches on 2D COF-based electrocatalysts.

Graphical Abstract

This review summarizes the strategies for improving the performance of two-dimensional (2D) covalent organic framework (COF)-based electrocatalysts and the recent researches on 2D COFs in the field of electrochemical conversion, to inspire and further pave the development of advanced electrocatalysts.
