New Titanium Oxide Compound for Photocatalytic Water Splitting, Hydrous Na16Ti10O28

Article Preview

Abstract:

Photochemical splitting of water into H2 and O2 using solar energy is process of great economic and environmental interest. In this study, we investigated novel photocatalytic compound, Na16Ti10O28, for water splitting. Na16Ti10O28 was prepared by solid-state reaction at 900 oC for 1 h. Prepared sample was characterized using powder X-ray diffraction, diffuse reflectance spectrum, and scanning electron microscopy. As-prepared Na16Ti10O28 sample is easily hydrated in water. Hydrous Na16Ti10O28 showed H2 evolution without co-catalyst.
