專利摘要

A method for preparing titanium dioxide particles co-doped with nitrogen and fluorine includes the steps of: mixing boric acid with ammonium fluorotitanate in an aqueous medium to form ammonium oxotrifluorotitanate; liquid-phase depositing the ammonium oxotrifluorotitanate on a silicon-containing substrate; and thermo-treating the ammonium oxotrifluorotitanate on the silicon-containing substrate at a temperature ranging from 300 to 1000° C.
