A visible‐light active TiO 2− x S x in rutile structure has been synthesized by means of a mechanochemical method. The method is composed of two steps: the first is grinding the mixture of sulfur and TiO 2 , and the second is calcining the ground sample at 673 K in an inert gas flow. XPS analysis confirms that sulfur has been successfully doped into TiO 2 . The calcined sample under irradiation of visible light with wave‐length over 510 nm has shown good performance for NO gas destruction, suggesting its high photograph‐reactivity.
