Electrochemical degradation of Acid Yellow 3 dye (AY3) in aqueous solution was investigated over a novel Ti/nanoSnO 2 -α-Fe 2 O3 electrode ssuccessfully fabricated by the cathodic electrophoretic deposition method. The surface morphology, elemental analysis, crystalline structure, and electrochemical properties of as-prepared nanoSnO 2 -α-Fe 2 O 3 films on titanium substrate surface were characterized by field emission scanning electron microscopy (FE-SEM) with an X-ray spectrometer attached, X-ray diffraction (XRD), linear sweep voltammetry (LSV), cyclic voltammetry (CV), and chrono-potentiometry (CP). The r esults showed that, compared to the traditional nanoSnO 2 electrode, the novel Ti/nanoSnO 2 -α-Fe 2 O 3 electrode with a porous morphology and without voids or cracks on the surface possessed higher electro-catalytic activity and electrochemical stability. To obtain maximum dye removal and t...
