Figure 4From: Flower-like ZnO-Ag2O composites: precipitation synthesis and photocatalytic activityDifferent experiments conducted to ZnO, Ag 2 O, and ZnO-Ag 2 O composites. Photocatalytic degradation of MO in the presence of (a) pure ZnO, pure Ag2O, and ZnO-Ag2O composites under UV light irradiation; (b) different weight ratios of ZnO and Ag2O in 90 min; and (c) UV–vis diffuse reflectance spectra of pure Ag2O, ZnO, and Ag2O/ZnO composites with variable contents.Back to article page
