Solar Hydrogen Production by Photocatalytic Water Splitting [BPN672]
Photocatalytic water splitting is the process of converting water into hydrogen and oxygen with solar energy using a photocatalytic material. When light is absorbed by the photocatalyst, an electron-hole pair is generated that interacts with water molecules in a surface reduction- oxidation reaction to decompose the water into hydrogen and oxygen. One of the greatest challenges in photocatalysis is engineering the photocatalytic material for high conversion efficiency and wide absorption spectrum in the visible light range. Metal oxide nanomaterials have demonstrated promising capabilities as photocatalysts due to their high surface area-to- volume ratios, ability to be densely grown at large scales, cost-effectiveness, and stability in water. This project aims to improve the performance of metal oxide nanomaterials for water splitting, in particular TiO2 nanowires and TiO2-coated carbon nanotubes, using innovative growth processes, co-catalytic materials, and band-gap manipulation.
