| Abstract: | s：Nano Bi2 O3 photocatalyst is prepared for using bismuth nitrate and ethylene glycol as raw materials by microwave method.We not only characterize the photocatalysts by XRD、UV and TEM means, but also study the properties of photocatalytic degradation to organic matter.It is discussed that catalytic efficiency changed with different initial concentration of the simulated pollutants.At last, the kinetic equations for photo-catalytic degradation are concluded under visible light irradiation that nanoscale Bi2 O3 to the three pollutants methylene blue, rhodamine B, methylene orange. |
