Electrochemical conversion of CO using metalorganic frameworks-based materials: A review on recent progresses and outlooks.

Global warming has been mainly attributed to the excessive release of carbon dioxide (CO) to the atmosphere. Several CO capture and conversion technologies have been developed in the past few decades with their own merits and limitations. Electrochemical conversion of CO is one of the most attractive techniques for combating CO emissions. However, the efficacy of the electrochemical reduction of CO hinges on the efficiency of the utilized materials (i.e., electrocatalysts). Metal organic frameworks (MOFs)-based materials have recently emerged as attractive tools for various applications, including the electrochemical conversion of CO. Although there are some review articles on CO capture and conversion using different materials, reviews focusing specifically on the electrochemical conversion of CO using MOFs-based materials are still comparatively lacking. Additionally, the field of electrochemical conversion of CO into valuable chemicals is currently gaining high momentum, requiring comprehensive and recent reviews, which would provide researchers/professionals with a quick and easy access to the recent developments in this rapidly evolving research area. Accordingly, this article comprehensively reviews recent studies on the electrochemical conversion of CO using pristine/modified/functionalized MOFs as well as composite materials containing MOFs. Additionally, single atom catalysts (SACs) derived from MOFs and their applications for the electrochemical conversion of CO has also been reviewed. Furthermore, obstacles, challenges, limitations, and remaining research gaps have been identified, and future works to tackle them have been highlighted. Overall, this review article provides valuable discussion and insights into the recent advancements in the field of electrochemical conversion of CO into chemicals using MOFs-based materials.
