Metal-organic Frameworks for CO2 Electroreduction

In the current chemical industry, only minor amounts of CO2 deriving from external sources are utilized. Actual chemical uses of CO2 have thus a minor impact on the reduction of GHG (greenhouse gasses) emissions. Several methods have been explored to address this issue, and CO2 elctroreduction is one of the most promising  However, scalable CO2 electroreduction still awaits catalysts that are both active and selective.

In this project, we explore the potential of MOF-based/derived catalysts in this field. Metal Organic Frameworks (MOFs) are crystalline solids consisting of infinite lattices built up of metal clusters and organic linkers, connected by coordination bonds of moderate strength. MOFs can be understood as metal clusters arranged in a crystalline lattice and these metal clusters are periodically separated by organic linkers in three dimensions. With external effects, such as thermal decomposition of MOFs, it is possible that this organic linker-supported structure undergoes collapse and the neighboring metal clusters aggregate into uniformly dispersed metal or metal oxide nanoparticles with the aid of the stabilization effect of the carbon base which evolves from the collapse of organic linkers. This process is what we call MOF-mediated synthesis, which will be the main pathway of synthesizing catalysts in this project.

Given the limited study on MOF applications in the field of CO2 utilization, the investigation to use MOFs in CO2 electroreduction will not only explore efficient ways to utilize CO2 but also broaden the research area of MOFs. Several practical considerations, such as reactor and electrolyte, will also be included in the scope of the project to maximize catalytic performance.
