Keywords: , , ,

This study focuses on the synthesis of TiO2 nanotube arrays and its application for hydrogen generation from photo-assisted water-splitting reaction. In the synthesis approach, an nt-TiO2/Ti/nt-TiO2 structure was synthesized using electrochemical anodization in fluorine (F-) based electrolyte. Further, this nt-TiO2/Ti/nt-TiO2 membrane structure was modified by preferential deposition of Pt and RuO2 co-catalysts on either side of the membrane. The selective placement of Pt and RuO2 on nt-TiO2/Ti/nt-TiO2 membrane structure could prove to be beneficial to achieve physical separation of H2 and O2 in a water photolysis reactor utilizing a single electrode scheme. One dimensional nanoarchitecture of TiO2 nanotube arrays has shown significant photocatalytic activity as compared to colloidal counterparts. The results obtained on the synthesis, characterization, and H2 generation from photo-assisted water-splitting reaction will be presented.
