Bismuth vanadate hollow spheres: Bubble template synthesis and enhanced photocatalytic properties for photodegradation

► Hollow sphere m-BiVO4 is simply synthesized via a simple hydrothermal method. ► Urea is used as bubble guiding surfactant. ► The formation process is bubble guiding attachment and repining. ► m-BiVO4 shows optimalizing activity for degradation of RhB and 2-propanol.
