TiO2 thin and thick films promoted with platinum and organic sensitizers including novel perylene diimide dyes (PDI) were prepared and tested for carbon dioxide reduction with water under visible light. TiO2 films were prepared by a dip coating sol-gel technique. Pt was incorporated on TiO2 surface by wet impregnation [Pt(on).TiO2], or in the TiO2 film [Pt(in).TiO2] by adding the precursor in the sol. When tris (2,2'-bipyridyl) ruthenium(II) chloride hexahydrate was used as sensitizer, in addition to visible light activity towards methane production, H-2 evolution was also observed. Perylene diimide derivatives used in this study have shown light harvesting capability similar to the tris (2,2'-bipyridyl) ruthenium(II) chloride hexahydrate.

Dye sensitized artificial photosynthesis in the gas phase over thin and thick TiO2 films under UV and visible light irradiation Ozcan, O.; Yukruk, F.; Akkaya, E. U.; Üner, Deniz (2007-02-15) Perylene diimide based organic sensitizers capable of electron generation under illumination were used to initiate gas phase photo reduction reactions on TiO2 thin and thick film surfaces. For comparison [Ru(Bpy)(3)](2+) dye sensitizers were also studied. The photo reduction Of CO2 was carried out under static conditions in the gas phase. TiO2 films were coated on hollow glass beads via a sol-gel procedure. Pt was incorporated on the films either by adding the precursor salt in the sol, Pt(in), or by wet im...
Photovoltaic performance of bifacial dye sensitized solar cell using chemically healed binary ionic liquid electrolyte solidified with SiO2 nanoparticles Cosar, Burak; Icli, Kerem Cagatay; Yavuz, Halil Ibrahim; Özenbaş, Ahmet Macit (2013-01-01) In this study, we investigated the effect of electrolyte composition, photoanode thickness, and the additions of GuSCN (guanidinium thiocyanate), NMB (N-methylbenimidazole), and SiO2 on the photovoltaic performance of DSSCs (dye sensitized solar cells). A bifacial DSSC is realized and irradiated from front and rear sides. The devices give maximum photovoltaic efficiencies for 70% PMII (1-propyl-3-methyl-imidazolium iodide)/30% (EMIB(CN)(4)) (1-ethyl-3-methyl-imidazolium tetracyanoborate) electrolyte composi...
Photon-to-carrier efficiencies of nanostructured zinc-phthalocyanine/fullerene thin films assessed by time-resolved terahertz spectroscopy Esentürk, Okan; Lane, Paul A.; Heilweil, Edwin J. (null; 2008-01-01) Blend and multilayer Zinc-phthalocyanine/fullerene thin films were investigated as model active layers for solar cells by Time-Resolved Terahertz Spectroscopy. A strong dependence on the blend ratio and multilayer nano-structure of the films was found
Pt/MWCNT and Pt/f-MWCNT Catalysts Preparation by Hydrogen Reduction and Impregnation Method: The Application to Methanol Oxidation Reaction Zabara, Mohammed Ahmed M; Gökağaç Arslan, Gülsün; Department of Chemistry (2016) In this thesis, multi-walled carbon nanotubes supported platinum nanoparticles (Pt/MWCNT) and functionalized multi-walled carbon nanotubes supported platinum nanoparticles (Pt/f-MWCNT) catalysts in different Pt percentages were prepared using impregnation method and hydrogen gas reduction. Firstly, multi-walled carbon nanotubes were functionalized using sonochemical method and characterized by Fourier transform infra-red spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), and acid base back titrati...
On the mechanism of photocatalytic CO2 reduction with water in the gas phase Üner, Deniz (2012-02-12) The mechanism of photocatalytic reduction of CO2 with H2O over Pt-TiO2 films produced by the sol-gel deposition over glass beads was investigated. The accumulation of significant amount of carbonaceous intermediate on the surface followed by deactivation indicated the rate limiting reaction is the water splitting reaction, similar to the natural photosynthetic systems. When gas phase hydrogen was allowed in the system, the carbonaceous intermediates were converted to methane at rates higher than the artific...
