Abstract：BiFeO3 microcubes were successfully synthesized via a controlled preprocessing process combined with subsequent hydrothermal reaction. The morphology features, crystal structure, and surface compositions of the BiFeO3 microcubes were characterized by scanning electron microscope, X- ray diffraction and X- ray photoemission spectra in detail. And time- dependent experiments were conducted to reveal the growth mechanism of the BiFeO3 microcubes. More attractively, the size of the cubes can be consecutively controlled from 8μm to 1. 5μm through adjusting the preprocessing temperature from 25℃ to 90℃. When employed as photocatalysts towards Rhodamine B degradation, the 1. 5μm samples showed the best catalytic activity.
