Covalent Organic Framework-Based Electrocatalysts for CO2 Reduction Reaction

Covalent organic frameworks (COFs), owing to their greater surface area, tuneable pore structure, functionality, and unique molecular architecture, have gained tremendous interest for various applications including; catalysis, electrocatalysis, gas sensing, sensor, adsorption, etc. Further, the high structural extent and the atomic-level distribution of active sites in COF have generated considerable attention due to their principle design and rapid screening of catalyst for particular application. In this context, firstly, we have summarized the latest progress on synthesis and characteristics properties of COFs then a thorough discussion is given on fine-tuning the characteristics features. In the next part, newly emerging COFs for catalysis and electrochemical carbon dioxide reduction reaction with superior catalytic activity have been extensively studied. Finally, we have provided a brief overview of the remaining challenges and future directions for enhancing catalytic performance.
