Thermal Ramping Rate during Annealing of TiO<sub>2</sub> Nanotubes Greatly Affects Performance of Photoanodes
Abstract
<jats:sec><jats:label /><jats:p>Herein, highly ordered TiO<jats:sub>2</jats:sub> nanotube (NT) arrays on a Ti substrate is synthesized in a fluoride‐containing electrolyte, using the electrochemical anodization method, which yields amorphous oxide tubes. The effects of different thermal annealing profiles for the crystallization of the amorphous TiO<jats:sub>2</jats:sub> NTs are studied. It is found that the temperature ramping rate has a significant impact on the magnitude of the resulting photocurrents (incident photon‐to‐current conversion efficiency [IPCE]) from the tubes. No appreciable changes are observed in the crystal structure and morphology of the TiO<jats:sub>2</jats:sub> NTs for different annealing profiles (to a constant temperature of 450 °C). The electrochemical properties of the annealed TiO<jats:sub>2</jats:sub> NTs are investigated using intensity‐modulated photocurrent spectroscopy (IMPS), open‐circuit potential decay, and Mott–Schottky analysis. The results clearly show that the annealing ramping rate of 1 °C s<jats:sup>−1</jats:sup> leads to the highest IPCE performance. This beneficial effect can be ascribed to a most effective charge separation and electron transport (indicating the least amount of trapping states in the tubes). Therefore, the results suggest that controlling the annealing ramping rate is not only a key factor affecting the defect structure but also a powerful tool to tailor the physical properties, and photocurrent activity of TiO<jats:sub>2</jats:sub> NTs.</jats:p></jats:sec>
