Abstract: BiFeO3 nano powders are prepared through carbon adsorption co-precipitation method, and their structure and properties are characterized by means of thermogravimetric analyzer, X-ray diffractometer, UV-Vis spectrophotometer and transmission electron microscope.The photocatalytic properties of BiFeO3 nano powders are also evaluated with the degradation of methyl orange as the probe reaction under the irradiation of a 1, 000 W dysprosium lamp.It is shown that activated carbon has effectively suppressed the agglomeration and sintering phenomena during the preparation of BiFeO3 powder.BiFeO3 powder calcined at 500℃ shows high crystallinity, uniform particle distribution and small particle size, over which the degradation rate of methyl orange can reach 91.2% within 120 min.
