The Influence of Tio2 Morphology and Doped PT on Hidrogen Production From Water with Photocatalytic Method

Abstract

The influence of TiO2 morphology and doped Pt on hydrogen production has been investigated. TiO2 nanotubes (TiO2 NT) were obtained by using combination of sonication and hydrothermal methods. Pt was doped on the surface of TiO2 NT by using photo-deposition method. TiO2 Degussa P25 nanoparticle was employed as comparison. Sonication was performed using ultrasonic cleaner for 60min then followed by hydrothermal treatment in a teflon lined stainless steel autoclave for 12 hours at 13 °C. TiO2 nanotubes were characterized by means of X-Ray Powder Diffractometer (XRD), Scanning Electron Microscope (SEM), UV-Vis Diffuse Reflectane Spectroscopy (UV-Vis DRS) and Brunauer-Emmet-Teller (BET) technique. A pyrex reactor was employed to conduct hydrogen production while methanol was used as sacrificial agent. The result shows by using Pt/TiO2 NT increased hydrogen production about 18 times than that of TiO2 NT without Pt doped
