Highly crystalline BiVO4 were prepared through a new low-temperature solid-state reaction (LSSR) by using Bi(NO3)(3)center dot 5H(2)O and NH4VO3 as raw source and monoclinic BiVO4 can be selectively prepared via such a reaction by controlling rubbing time. The as-prepared BiVO4 particles were characterized by XRD, SEM, FTIR and DRS. Meanwhile, controlled experiments show that rubbing Lime, drying time and water content play important roles in the formation of monoclinic BiVO4. In addition, this method has advantages such as relatively low synthesis temperature, low power consumption, simple operation and environment friendly. Finally, the mechanism of LSSR has been primarily discussed.
