제목 The Hydrogen generation based on photo-electrochemical splitting of water by TiO2 nanotube
초록 Titania (TiO2) is well-known as a semiconductor with photocatalytic activities, so it can be employed in many areas such as environmental purification, gas sensors, photovoltaics and generation of hydrogen gas. Titania nanotube can be adopted as a electrode to generate hydrogen in water split system. In this study, titanium oxide nanotube arrays were fabricated at 20V in mixed solutions of H3PO4, HF and NaNO3. These nanotube annealed in air atmosphere. This nanotubular TiO2/Ti electrode can be perfectly acted as a photo-anode for photo-electrochemical splitting of water. Various characterization techniquesare used to study the surface morphology, phase and photo-current density.
