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 0,57 wt% Pt exhibited the highest photoelectrochemical properties. Furthermore, high surface area, small particle size enhanced visible-light absorption as well improved charge transfer separa...
