Article Preview

Cu2O/PVA/chitosan composite films were prepared successfully by reduction-precipitation method and tape casting process. The composite films were characterized by TEM, SEM, XRD and FT-IR. The characterization results showed that Cu2O particles were 200-300 nm in diameter and in situ formed on PVA-chitosan blend films. The visible-light photocatalytic decolorization behavior on Cu2O/PVA/chitosan was evaluated using reactive brilliant red X-3B (X-3B) as a model pollutant. The influences of various experimental factors on X-3B decolorization were investigated. Results showed that the decolorization rate of X-3B could reach 99.8% after 50 min irradiation under the conditions of initial dye concentration 20 mg/L, catalyst amount of 0.8 g/L, H2O2 dosage of 4.04 mmol/L and pH 5.6. After composite film was reused for 5 times, the decolorization rate of X-3B could still reach more than 90% after 110 min irradiation
