Abstract Covalent–organic frameworks (COFs) based heterojunctions photocatalytic have showed great potential for CO 2 upcycling. Currently, significant progress has been made in developing such photocatalysts, yet a comprehensive understanding of this field remains lacking. This review systematically explores the inherent relationship between COF‐based heterojunction innovations and CO₂ reduction, aiming to establish structure–performance–mechanism correlation that guides design high‐efficiency catalysts. First, fundamentals, mechanisms, related principles conversion, as well advantages COFs application, are thoroughly introduced. Then, state‐of‐the‐art applied reduction discussed from following critical aspects: interfacial engineering, spatial charge transfer regulation, active component hybridization, half‐reaction kinetic optimization, sites engineering. Subsequently, systematic overview characterization techniques research methodologies probing catalyst structures in‐depth reaction mechanisms is outlined. Finally, challenges further development direction proposed. It expected can provide powerful guidance reference toward exploiting high‐performance photocatalysts conversion.

Abstract Covalent organic frameworks (COFs) have latterly emerged as a promising platform for devising electrode materials used to acquire high‐performance lithium‐ion batteries (LIBs). However, the preparation of COFs with fast redox kinetics, high‐efficiency utilization active sites, superior stability, and high conductivity remains challenge. Herein, thiophene‐based bipolar‐type (denoted TT‐TPDA‐COF) featuring extended conjugation, rich multiple redox‐active sites (C─S, C─N, C═N), hierarchical micro‐mesoporosity is synthesized. TT‐TPDA‐COF exhibits significantly increased density enhanced electrical compared its corresponding counterpart (Np‐TPDA‐COF). Remarkably, when LIBs cathode, it shows exceptional specific capacity up 309 mA h g −1 at 200 , surpassing that Np‐TPDA‐COF (195 ), energy 714 W kg superb rate property (182 5000 impressive preservation 84.3% after cycles . Additionally, predictable application prototype has been proved by dual‐ion full cells assembled using cathode. Furthermore, storage mechanism comprehensively revealed in/‐ex situ studies theoretical calculations.
