Abstract
The invention provides a process for the preparation of bismuth oxyhalide, comprising a precipitation of bismuth oxyhalide in an acidic aqueous medium in the presence of a reducing agent. Also provided are bismuth oxyhalide compounds doped with elemental bismuth Bi. The use of Bidoped-bismuth oxyhalide as photocatalysts in water purification is also described.
