Abstract: Ionic liquid-assisted hydrothermal technique was used for the synthesis of Clinobisvanite (m-BiVO4) micron-sheet crystal and the crystal structure was refined by Rietveld method. m-BiVO4 has a monoclinic symmetry with space group I2/b. Synthesized products were characterized by XRD, IR and SEM methods. The primary results indicated that the amount of ionic liquid and pH value played crucial roles in controlling the morphology of as-prepared m-BiVO4. Particularly, the amount of ionic liquid [BMIM]Br can effectively control the shape of m-BiVO4 by the adsorption on the (001) plane of m-BiVO4.
