摘要：
Bismuth vanadate (BiVO4) photocatalyst was synthesized by microwave method at 500Watt for 2, 4 and 6min. The product was characterized by X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). The photocatalytic degradation of methylene blue (MB) over BiVO4 photocatalyst was investigated by Ultraviolet-visible spectrometry (UV-Vis). Multi-phase of monoclinic and tetragonal structure of BiVO4 was obtained. The morphology and particle size of BiVO4 showed a spherical-like particle with diameter of 200-400nm. The photocatalytic activity of BiVO4 photocatalyst prepared at 500Watt for 4min showed the highest degradation of MB under UV light irradiation.
