Synthesis of MoO_3 nanostructures and their photocatalytic properties

摘要

Different morphologies of molybdenum trioxide have been synthesized via low-temperature liquid phase method, hydrothermal synthesis and the direct decomposition method. Fourier transformed infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscope (SEM) were employed to characterize the as-synthesized products and the photo catalytic degradation properties were studied for different nitrogen of dyes. The results indicate that the discoloration rate of methylene red was the best and it could be more than 90 percent in the same conditions. Therefore, the synthesized MoO_3 powder is a kind of photocatalayst with excellent performance.
