Synthesis of gold-doped TiO2 nanotubes

Nanostructured materials have been the focus of scientific research due to their unusual physical and chemical properties. Therein, nanoscale TiO2 is one of the most investigated materials owing to its significance for applications in heterogeneous catalysis, nonlinear optical devices, gas sensors and photoelectrochemical solar cells.Many studies have been devoted to the improvement of TiO2 activity by doping noble metals. Among them.
