Surface modification of titanium dioxide (TiO2) with silver and bismuth was performed to increase the photocatalytic degradation of methylene blue (MB). The effect of initial calcination temperature, reaction time, catalyst loading and initial pH value was studied. The physicochemical properties of as-prepared samples were characterized by XRD, UV-Vis DRS, TG-DTG and XPS. The results indicate that...
A silver germanium oxide, Ag 2 GeO 3 , was developed as a novel photocatalyst for degradation of organic dyes. The chemical composition of the sample was investigated via the SEM/EDX, ICP-AES, and TG-DTA techniques. The general activity of the material was characterized by testing the photodegradations of typical organic dyes, such as Methylene Blue (one of the heteropolyaromatic dyes),...
