Abstract

Titanium dioxide Hombickat UV100 was used as semiconductor for hydrogen production reaction without and with modification by 0.5% single walled carbon nanotubes SWCNTs and platinum Pt. the modification includes synthesize binary composites with SWCNTs by sonochemical addition while with Pt was accrued by photo deposition method. Structural properties and morphology of the synthesized materials SWCNT/UV100, UV100: Pt and ternary composites SWCNT/UV100: Pt with pristine UV100 were characterized by x-ray diffraction, UV-visible diffraction and Fourier transform infrared spectroscopy FTIR. The results showed that SWCNTs reduce the activities of UV100 in producing H2 from solution 10% MeOH/H2O while in the ternary composites SWCNT/UV100: Pt the SWCNTs play very important roles in increase the activity of UV100 with Pt to more than 20%. The role of SWCNTs was related to dispersion Pt with less agglomerates as compare with UV100: Pt and that create more active cites on the surface of UV100-TiO2.UV100 with Pt to more than 20%. The role of SWCNTs was related to dispersion Pt with less agglomerates as compare with UV100: Pt and that create more active cites on the surface of UV100-TiO2.
