Photochemical studies on N-doped TiO2 single crystals - Fundamental Investigations of Water Splitting on Model TiO2 (Mike Henderson's BES Project - 48526)


EMSL Project ID
9093

Abstract

This program's overall goals are aimed at the development of new energy sources for the 21st century. Hydrogen has considerable potential as an alternative fuel. Research includes examining the fundamental properties of heterogeneous photocatalytic water splitting on ion-doped TiO2 single crystal surfaces (with and without noble-metal loading) in a concerted approach that employs: (a) controlled doping using molecular beam epitaxy and ion implantation, (b) characterization using state-of-the-art techniques, (c) theoretical modeling using DFT methodologies, (d) photochemistry and photodynamics using UHV-based surface science methods, and (e) photocatalytic performance tests. This effort directly addresses two key elements (Design of Catalysts on the Nanoscale and Solar Hydrogen Production) of the Hydrogen Fuel Initiative. Please contact Mike Henderson, project manager, for further information. Assumptions - The DOE client (Basic Energy Sciences) expects us to conduct fundamental research to further our knowledge in areas of importance to DOE's mission, and to disseminate this knowledge through publications in peer-reviewed journals and presentations of results at scientific meetings.
