Bismuth vanadate (BiVO4) mainly has three crystal structures: monoclinic scheelite,tetragonal zircon and tetragonal scheelite phase[1].Among the three kinds of three crystal structure,monoclinic scheelite BiVO4 crystals were often reported a superior photocatalytic performance in the photochemical degradation and O2 evolution reaction[ 2,3 ].In addition,morphology also has an impact on the photocatalytic activity.It is expected that if the morphology can be controlled,then their properties would be adjustable to meet different needs.
