Published: March 24, 2025

Abstract COFs have become the most attractive frontier research area in heterogeneous catalysis. Since geometry and electronic structure of are largely determined by their microenvironment, which turn determines performance electrocatalytic processes, precise integration atoms COF building blocks to achieve pre‐designed composition, components functions is core. This paper focuses on structural design, synthesis, mechanism application CO 2 RR (types RR, evaluation indicators relationship between performance). In addition, we also explore challenges faced corresponding solution strategies. Finally, highlighting prospects regulation, hope provide inspiration for further development applications.

Covalent organic frameworks (COFs) are increasingly being utilized in photocatalysis due to their programmable band gaps and pore geometries. Flexible COFs currently of interest for selective sorption, though use has received little attention date. Herein, we propose a strategy modulating the flexible units facilitate efficient charge carrier separation transfer during photocatalysis. Rotational freedom linkers our led controllable local curvature, thereby optimizing optoelectronic properties boosting photocatalytic activity. One developed (COF-3) showed excellent performance uranium removal from contaminated groundwater tap water. Mechanistic studies revealed that COF-3 photocatalytically generated H₂O₂ under visible light irradiation water, which transformed UO₂²⁺ solid (UO₂)O₂·2H₂O through redox pathway. The results demonstrate an effective design towards COF photocatalysts water potentially many other applications.
