Bismuth oxyhalide compounds useful as photocatalysts

摘要

Mixed chloride-bromide bismuth oxyhalide compounds, with the molar ratio chloride:bromide being equal to or greater than 1:1, in the form of microspheres exhibiting flower-like surface morphology, are disclosed. Processes for preparing the compounds, formulations of the compounds and a method for purifying water using said compounds are also disclosed.
