Description

We design and synthesize innovating nanomaterials for fuels production and environmental remediation. Areas of concern include: (1) thermal and photo-assisted degradation of organophosphorous or perflourinated compounds and (2) solar-driven fuels synthesis (i.e. water splitting and carbon dioxide reduction). One of the biggest barriers limiting the practicality of both solar fuels production and sunlight-assisted chemical degradation is the lack of photocatalytic materials that efficiently capture and convert sunlight to drive targeted chemistry. Work focuses on using plasmonic nanostructures to introduce visible-light driven activity into wide-bandgap semiconducting photocatalysts to expand their applicability for solar-driven applications. Fully exploiting plasmonic materials for photocatalytic applications requires detailed analysis of the materials design parameters that control plasmonic-sensitization efficiency. Research efforts will be focused on: 1) synthesis of composite catalysts coupling high-surface-area oxide supports with embeded plasmonic nanostructures; 2) quantifying the sensitization efficiency (i.e. carriers generated per photon) of the plasmonic nannostructures as a function of structural properties (composition, size, shape, weight loading); and 3) determining the extent to which plasmonic sensitization improves catalytic turnover for reactions of interest.
