Catalyst Development for Polymerization and CO₂ Capture, Storage and Upcycling to High Value Materials

Current strategies to reduce CO2 emissions are insufficient—both point-source and direct-air-capture (DAC) must be considered to mitigate excessive atmospheric CO2 concentrations. Given the urgency of climate change issues and the immense challenges of developing viable methodologies for CO2 conversion, we posit that understanding structure–property relationships of organic/inorganic molecular reactivity across multiple length scales will lead to the evolution of remarkably efficient transformations of CO2 and revolutionize chemistries to control the fate of this greenhouse gas. Thus, we sought to investigate families of superbases (SBs) that serve as CO₂ mitigating agents. This talk will focus on describing the wide-scope reactivity of a family of modular SBs that can be exploited in a variety of chemical transformations of CO₂ from dilute and pure gaseous sources as well as polymerizations. We found that the SBs can form zwitterionic complexes to activate CO₂, which can be readily mineralized into metal carbonates. Importantly, the highly reactive nature of SBs renders them widely useful to upcycle CO₂ into high value products.
