文摘

C4+ and S4+-codoped titanium dioxide (TiO₂) having a rutile phase was prepared. By doping C4+ and S4+ ions into a TiO₂ lattice, the absorption edge of rutile TiO₂ powder was largely shifted from 400 to 700 nm. 2-Methylpyridine and methyleneblue were photocatalytically oxidized at high efficiency on C4+ and S4+-doped TiO₂ under visible light at a wavelength longer than 5 nm.
