Abstract

Nitrogen-doped yellowish rutile titania prepared by high energy ball milling of P-25 titania - HMT (Hexamethylenetetramine) mixed powders followed by calcination in air at 400°C possessed two absorption edges around 400 and 540 nm and showed excellent photocatalytic ability for nitrogen monoxide destruction under irradiation of the visible light of wavelength > 510nm.
