Catalysis: An Enabling Science for Sustainable Chemistry

Catalysis is also a foundational pillar for sustainable chemical processes; the discovery of highly active, environmentally benign catalytic processes is a central goal of Green Chemistry.  The development of new families of catalysts continues to drive innovation in Chemistry and Materials Science.  Polymers are ubiquitous and are highly useful modern materials.  Catalysis has proven the enabling science for polymer synthesis, as well as a key strategy for generating new monomers from petrochemical and renewable feedstocks. Biodegradable polymers derived from renewable resources provide an attractive alternative to many petrochemical thermoplastics due to their attractive and improving cost/performance characteristics, their application as biomedical materials, and their potential to mitigate the environmental impact of discarded plastic waste in landfills.  We have developed new selective catalytic methods for the selective oxidation of biomass-derived polyols, including unprotected carbohydrates.  Mechanistic studies have illuminated new pathways for aerobic oxidation reactions.   With Jim Hedrick of IBM, we have developed a new family of environmentally benign organic catalysts for the synthesis of biodegradable and biocompatible plastics. Mechanistic and theoretical investigations generated new scientific insights on the diversity of mechanistic pathways for organocatalytic polymerization reactions and the opportunities that these new insights have created for the synthesis of well-defined macromolecular architectures.
