| Abstract: | Hexagonal phase MoO3 was synthesized by hydrothermal method at low temperature,which was characterized by XRD,SEM,FI-TR and TG.After calcined at 350 ℃,hexagonal MoO3 was changed to orthorhombic MoO3.UV-Vis spectral was used to measure band gap of the as-synthesized products.The photocatalytic activity was evaluated by degradation of methylene blue,the decolorization rates of methylene blue reached 94.6% and 81.2%,respectively.The result showed the photocatalytic activity of hexagonal MoO3 was better than orthorhombic MoO3. |
