Abstract
Many elements have been used to dope titanium dioxide (TiO2) so that it absorbs light in the visible region of the solar spectrum. We have synthesized, for the first time, (S,N)‐codoped rutile‐TiO2 photocatalyst using a hydrothermal method and subsequent nitridation under NH3 flow. The (S,N)‐codoping causes the absorption edge of TiO2 to be shifted to the longer‐wavelength region and two optical absorption bandgaps in the visible‐light region. (S,N)‐codoping has a better photocatalytic activity than S‐doping and N‐doping for degradation of methylene blue solution under visible light.Keywords
