Comparison of synthetic routes for large-scale synthesis of spherical BiVO₄ with photocatalytic and superhydrophobic properties

Abstract

Abstract The spherical BiVO4 in tetragonal and monoclinic scheelite phases have been prepared through five general methods by using K6V10O28·9H2O as self-sacrifice templates. The morphology of these BiVO4 is kept spherical because of K6V10O28·9H2O as self-sacrifice templates. The microwave-assisted synthesis of tetragonal BiVO4 is convenient, and ultrasonic synthesis is the best choice for the synthesis of monoclinic BiVO4. BiVO4 has been prepared by five general methods using decavanadate (K6V10O28·9H2O) as vanadium source. And the morphology of these BiVO4 is spherical
