An electrolyte used in this work was Bisphenol A (BPA). Degradation was carried out under electrochemical oxidation, photolysis and photoelectrochemical. Characterization techniques utilized were: ultraviolet–visible (UV) diffuse reflectance analysis, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDX), Raman, thermal gravimetric analyzer (TGA), and X-ray diffractometry (XRD). SEM morphologies, EDX and the XRD patterns showed a good mix and disperse among nanocomposites in terms of the formation of TiO2-Ag2O/EG. Degradation analysis revealed TiO2-Ag2O/ EG as the best nanocomposite for degradation of azo dyes from the wastewater. On a relative view of engaged techniques, photoelectrochemical revealed to be worthwhile.
