Abstract

Visible light-active BiVO4 photocatalyst was successfully synthesized through a cyclic microwave irradiation method without further calcination process. The synthesized powder was characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS). The BiVO4 powder revealed an excellent photocatalytic degradation of methylene blue under visible light irradiation. The degraded methylene blue was monitored by both UV-Vis spectrophotometer and absorbance in RGB channels. Similar decolorization percentage as well as pseudo first-order rate constant were achieved with high accuracy and sensitivity. The light absorption in RGB channels is an alternative simple and cartable way requiring lower amount of sample for detecting the dye degradation photocatalytic activity.
