چکیده انگلیسی
The stratified WO3/TiO2 thin films have been deposited onto glass and FTO coated glass substrates using simple chemical a spray pyrolysis method. The structural, morphological, compositional and photoelectrocatalytic properties of the stratified WO3/TiO2 thin films are studied. The photoelectrochemical (PEC) study shows that, both short circuit current (Isc) and open circuit voltage (Voc) are (Isc =1.192Â mA and Voc =0.925Â V) relatively high at 50Â ml spraying quantity of TiO2 solution on pre-deposited WO3. XRD analysis confirms that films are polycrystalline with monoclinic and tetragonal crystal structures for WO3 and TiO2 respectively. Specific surface area of 72.14Â m2Â gâ1 is measured by Brunauer-Emmett-Teller (BET) technique. Photoelectrocatalytic degradation of benzoic acid (BA) dye in aqueous solutions is studied. The end result shows that the degradation percentage of benzoic acid (BA) using stratified WO3/TiO2 photoelectrode has reached 66% under sunlight illumination after 320Â min. The amount of degradation is confirmed by COD analysis.
