Abstract
TiO2 has been the focus of enormous research activities during the last two decades. In the form of titania nanotube aligned arrays (TNA), the material is now a prominent candidate for the production of hydrogen from water through photo-catalysis. Aiming at the use of sunlight as the sole source of energy, great efforts have been done by the researchers to decrease the band-gap of TNA’s while keeping the recombination process minimal. Here, we will present our latest discoveries regarding the improvement of the photo-catalytic properties of TNA’s through the implementation of multiple doping or use of special quantum dot decorations. Multiple doping (three dopants) through a special one-step chemical route may result in a synergetic effect leading to the reduction of band-gap energy. Special novel quantum dot decorations may also lead to similar highly enhanced photo-catalytic behaviors which will be alluded to in the presentation.
