Photocatalytic study of silver and bismuth codoped zinc oxide by spray pyrolysis

Abstract

The bismuth and silver co-doped zinc oxide was prepared by spray pyrolysis at 450°C. With the increasing of silver, different state can be specified from the 10K photoluminescence analysis. The improved photocatalytic activity can be observed for thin film with suitable silver doping through the photodegradation of congo red under UV-light irradiation.
