Research Progress of CO₂ Reduction Catalyzed by MOF-based Materials

Transformation of CO₂ into valued-added products is an indispensable part of accomplishing carbon neutrality. Metal-organic frameworks (MOFs) are believed to be promising catalysts for the utilization of CO₂, attributing to their well-defined porous structure, abundant active sites and vastly high tunability. The latest researches of MOF-based functional materials as photo- and electro-catalysts for the reduction of CO₂ were summarized in this paper. Novel catalysts were divided into three categories, active MOF, MOF composites and MOF derivatives to facilitate the discussion of enhanced activity. The reason of improvement was ascribed to their well-designed physicochemical properties, especially the property of metal sites, coordination situation and morphology of materials. The future progress of research of MOF-based CO₂ reduction catalysts was hence proposed.
