INORGANIC AND MATERIALS CHEMISTRY

ENERGY CATALYSIS AND SOLAR-TO-CHEMICAL CONVERSION

New catalysts for carbon-neutral energy conversion processes are essential to addressing climate change and rising global energy demands. We are taking a unified approach to this small-molecule activation problem by developing molecular inorganic, biological, and materials catalysts for carbon dioxide reduction and water splitting that can be used in parallel under environmentally green, aqueous conditions. Biology and materials science provide concepts as well as components to develop new solar-to-chemical conversion processes. Molecular materials derived from metal-organic and covalent organic frameworks and related porous cages, along with molecular-nanoparticle composites, complement molecular inorganic catalyst designs.
