The Bi₂O₃ was prepared from Bi(NO₃)₃·5H₂O, followed by calcination of its alkali salt. The Bi₂O₃ was used as photocatalyst in photocatalytic decoloration of dyes. The results showed that the Bi₂O₃ exhibited a better photocatalytic activity under illumination of sunlight than that illuminated by Hg-lamp.
