Enhanced Photocatalytic Activities of Ag/ZnO Powders Modified by Diblock Copolymer

Abstract:

Ag/ZnO powders were synthesized through a precipitation method, using poly(ethylene oxide)-block-poly(propylene oxide) as stabilizer. X-ray diffraction patterns of all prepared powders showed a mixed phase of Ag and ZnO. The existence of metallic Ag on the surface of all prepared ZnO powders was confirmed by X-ray photoelectron spectroscopy. Their photocatalytic activities were investigated through the degradation of a methylene blue solution under blacklight illumination. The Ag/ZnO prepared from the Zn²⁺ solution containing 7 mol% of Ag⁺ had the highest photocatalytic activity and this also showed better photocatalytic activity than a commercial ZnO powder.
