| Abstract: | The triclinic FeVO4 was prepared through liquid-phase precipitation and characterized using XRD and SEM.Experiments were carried out using methyl orange(MO) as the pollutant object to evaluate the photocatalytic activity of FeVO4 powder.A UV light with the wavelength at 253.7nm was used as the energy source for the photocatalytic experiments.The effects of catalyst loading,initial MO concentration,light intensity and pH value on the degree of photo degradation have been investigated. |
