Abstract

Fibrous SrTiO₃ particles with nanosized crystals on the surface were prepared by hydrothermal reaction method using strontium hydroxide octahydrate and protonic layered tetratitanate as raw materials. SrTiO₃ could be formed by two different ways simultaneously, one way is direct reaction between H₂Ti₄O₉ and Sr(OH)₂ and the other is two steps reaction involving transformation of H₂Ti₄O₉ to monoclinic TiO₂ and reaction between TiO₂ and Sr(OH)₂. The photocatalytic activity of fibrous SrTiO₃ near ultraviolet light range (λ > 290 nm) was 1.5 times greater than that of SrTiO₃ powder.
