Materials for Electro- and Photoelectro-chemical Conversion and Storage
The interconversion of electrical and chemical energy is the basis for the operation of devices including fuel cells, batteries, supercapacitors and electrochemical reactors. There is also great interest in the conversion of solar energy into energy via photoelectrochemical processes. New, better performing materials and chemistries will drive increased use of electrochemical and photoelectrochemical conversion and storage devices. Research in our group aims to rationally design materials for these applications and establish the scientific basis for development of new functional materials. Results from our research could lead to advances in areas including (sponsors):
Supercapacitors: highly conductive nitrides/carbides with high surface areas and capacitances (ARO, TARDEC)
Redox Flow Batteries: non-aqueous chemistries to significantly increase cell potentials and energy densities (NSF)
Lithium Ion Batteries: new fabrication methods and materials to enhance energy and power densities
Chemoselective Electrochemical Hydrogenation of Organics: high activity electrocatalysts with high selectivities (USDA)
Photoelectrochemical Cells: nanotube photocatalysts with high water oxidation activities and quantum efficiencies (HETL)
Nanostructured Catalytic Materials
By some estimates more than 90% of all commercial chemical products including polymers and fuels involve catalysts at some stage in their manufacture, and the products account for more than $1 trillion annually. The quest for better performance is driving research into new catalyst formulations and nano-architectures. Our group uses experimental and computational tools to rationally design and synthesize new nitride, carbide and oxide based materials with enhanced performance. Reactions of interest include those involved in the hydrogen production, biomass and CO2 conversion to fuels and chemicals, and automotive exhaust after-treatment. Our research could lead to advances in areas including (sponsors):
Water Gas Shift: high surface nitride/carbide supported metals with high activities and durabilities (NSF)
Fischer-Tropsch Synthesis: high surface nitride/carbide supported metals with high activities and selectivities (NSF)
CO2 Hydrogenation: cascading heterogeneous/homogeneous catalysts with high activities and selectivities (NSF)
Hydrodeoxygenation in Supercritical Water: novel catalysts for the removal of oxygen from biomass derived organics
Exhaust After-treatment: low cost, non-precious metal catalysts for the oxidation of NO (GM, NSF)
