The photoelectrochemical performance of Ag coated CeO2 functionalized TiO2 nanotube arrays (AgCeTNT) is investigated here. sample prepared via three steps, such as synthesis by electrochemical anodization, functionalization hydrothermal and coating Successive Ionic Layer Adsorption Reaction (SILAR) method. X-ray diffraction (XRD) analysis showed the anatase phase formation after annealing nanot...
