FABRICATION OF TITANIUM DIOXIDE (TiO2) NANOTUBE ARRAYS DOPED WITH PLATIN (Pt) AND THEIR PHOTOELECTROCHEMICAL CHARACTERISTICS
Keywords:Nanotube array, Platin, Titanium dioxide, photoelectrode
In this work, Titanium dioxide (TiO2) nanotube arrays doped with Platin (TiO2/Pt) was successfully synthesized at low temperature by anodic and chemical reduction methods. Results showed that Pt/TiO2 NTAs with 0,57 wt% Pt exhibited the highest photoelectrochemical properties. Furthermore, high surface area, small particle size and enhanced visible-light absorption as well as improved charge transfer and separation are believed to be responsible for the improvement of photocatalytic activity of the doped materials.
