Fabrication of Hollow Anatase Structure by Using Sea Wool Sponges

摘要

Highly porous carbon-doped anatase was produced by a simple and time-saving method. The product was prepared by using sea wool sponges and a titanium-contained organic solution. The intermediate product was pyrolyzed sponges coated with amorphous anatase. When further annealed, the final product was an entirely carbon - anatase product with the original structure of sea wool sponges. The struts in the carbon - anatase product were hollow with wall thickness less than 300 nm. Cathodoluminescence measurement showed that this C-TiO_2 product was sensitive to visible light.
