Synthesis of TiO_2 Nanotube Arrays for Hydrogen Production From Photo-Assisted Water Splitting Reaction

摘要

This study focuses on the preparation of Pt sensitized TiO_2 nanoparticles and nanotube arrays and their application in hydrogen generation from photo-assisted water-splitting reaction. For the synthesis of TiO_2 nanotubes arrays an electrochemical anodization in fluorine (F-) based electrolyte was adopted. Further, these TiO_2 nanotubes arrays were sensitized with Pt using hexachloroplatanic acid. The presence of platinum on the surface of TiO_2 nanotubes arrays provided the reductive sites for the hydrogen generation in a photocatalytic cell. The effectiveness of Pt sensitized TiO_2 nanoparticles towards the H_2 generation from photo-assisted water-splitting reaction was compared with Pt sensitized TiO_2 nanotube arrays.
