Fig. 13From: Synthesis of ZnO/Si Hierarchical Nanowire Arrays for Photocatalyst ApplicationAbsorption spectra of degraded MB aqueous solutions as catalyzed by sample ALD in Ag/TiO2 coating layer under irradiation of UV light, in which 0, 1st, 2nd, and 3rd hours represent spectrum of MB solution before photodegradation, after photodegradation in the 1st, 2nd, and 3rd hours, respectively. The inset shows the enlarged image of the absorption peakBack to article page
