Abstract
Titania mesocrystals were produced in the presence of polyethylene glycol 400. The doping of the mesocrystals with a small amount of vanadium was shown to increase the photocatalytic activity in comparison with undoped anatase mesocrystals. It was experimentally determined for the first time, using mild ultrasonication of the material, that the photocatalytic reaction of the decomposition of crystal violet occurs throughout the surface of the titania mesocrystals.
