The flexible route for the electrosynthesis of visible light active CdxZn1-xOnanostructures by sequential anodic dissolution ofmetallic electrodes

A flexible route for the electrosynthesis of visible light active CdxZn1-xO nanostructures has been proposed.Various nanostructures were prepared by anodic dissolution in 0.1M Me4NCl by using an applied potentialof 15V for 30min. The prepared nanostructures were characterized by diffuse reflectance UV-Vis spectroscopy(DRS), Fourier transforms infrared spectrometry (FT-IR), X-Ray diffraction (XRD) and scanningelectron microscopy (SEM). The results showed that the crystalline structure, morphology, and energyband gap of the products can be finely adjusted only by varying the duty cycle of the anodeswitching.The visible light activity of the obtained nanostructures was investigated using methyl orange as a modelorganic pollutant. It was found that the proposed method can be used to obtain very effective CdxZn1-xOphotocatalysts by fine tuning of the morphology and energy band gap. The prepared photocatalyst retained80% of its original activity after 5 replicated uses.
