| Anatase TiO2 nanosponges have been synthesized by anodization of Ti, and Li+ cations have been inserted in these nanostructures. The influence of hydrodynamic conditions (Reynolds number, Re = 0 to Re = 600) during anodization has been studied. Li-Doped TiO2 nanosponges were characterized by field emission scanning electron microscopy (FE-SEM), Raman confocal microscopy, electrochemical impedance spectroscopy (EIS) and Mott-Schottky analysis (M-S). The photoelectrochemical performance and resistance to photocorrosion were also measured. Li-TiO2 nanosponges proved to be better photocatalysts for water splitting than Li-TiO2 nanotubes. Moreover, the photoelectrochemical behavior of the Li-doped nanosponges improved as the Reynolds number increased. | |||
