Abstract

Fibrous SrTiO₃ were prepared by two kinds of methods: solid state reaction of fibrous TiO₂ and SrCO₃ and hydrothermal reaction of Sr(OH)₂ and H₂Ti₄O₉. Fibrous SrTiO₃ prepared by hydrothermal reaction consisted of nanosize crystals with high crystallinity and showed higher photocatalytic activity than that prepared by solid state reaction. Nitrogen could be doped in fibrous SrTiO₃ by calcining the powder in the atmosphere of NH₃ at 600^oC. The nitrogen doped fibrous SrTiO₃ exhibited the excellent photocatalytic NO destruction capability in the visible light range.
