Abstract
For the precursor, powders were calcined at 773 K (500 °C) for 1 hour. The anatase TiO2 and ZnO appear as the predominant and minor phases, respectively, when the precursor powders are obtained at pH 5. The phases of Zn2Ti3O8, anatase TiO2, and ZnO coexist for the precursor powders obtained at pH 7. In addition, the Zn2Ti3O8 and ZnO are the predominant and minor phases, respectively, for the precursor powders obtained at pH 9.
