N2 - Titanium dioxide (TiO2) nanotube is a one-dimensional (1D) form of TiO2 in nanometer scale with numerous applications. This study aims to determine the correlation between the properties of TiO2 nanotube and its photocatalytic performance. The properties of TiO2 nanotubes which include crystallite size, surface area, band gap energy, phase composition and doping elements affect its performance either for better or worse. This study confirmed that the optimum level for calcination process for the nanotubes was in the temperature range of 400-600°C, while the largest surface area corresponded strongly with high level of photocatalytic activity. Furthermore, in terms of band gap energy, the nanomaterial with the smallest value does not necessarily have the best performance although, it was important for the nanotubes to have small value. From the results obtained, it was observed that phase composition plays a key role where the highest photocatalytic performance was achieved by the nanomaterial with high anatase-low rutile combination. It was discovered that there were several variations regarding the optimal crystallite size needed to achieve the highest photocatalytic performance. However, doping was found to be beneficial for enhancing the photocatalytic performance of TiO2 nanotubes. Furthermore, it was observed that in order to obtain the best photocatalytic performance, the properties of TiO2 nanotubes should work in "harmony"since they had no advantage over each other.
