Synthesis of high-surface-area titanium dioxide by sol-gel process for DSSC

Abstract

Mesoporous TiO 2 material was synthesized from dissolution ilmenite as well as from titanium chloride precursor via a sol-gel process in acidic aqueous solution. The properties of these materials were characterized with several analytical techniques including scanning electron microscopy (SEM), transmission electron microscopy (TEM), wide angle X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) analysis, and Barrett-Joyner-Halenda (BJH) analysis. The mesoporous TiO 2 materials calcinated at various temperatures were found to have high value surface areas. The photovoltaic of photo-anode build from the mesoporous TiO 2 was characterized with I-V Keitley Multimeter, and it was found that photovoltaics fabricated using the mesoporous TiO 2 have a good performance. Such a high photovoltaic activity is explained with large surface area and small crystal size.

Development of inorganic composite material based TiO2for environmental application

“…Complete polymerization and loss of solvent lead to the transition from a liquid sol into a solid gel phase. Titanium dioxide has been reported synthesized by sol-gel method using titanium tetrachloride, titanium alkoxide, and titanyl sulfate as well as titanyl chloride precursors [28,29,30]. If TiO 2 is reacted with a strong base it will hydrolyze, this is splitting the polymer chains of TiO 2 (depolymerization) by the presence of OH-groups.…”

Optimized Ilmenite Leachate by Wet Mechanical Activation for the Synthesis of TiO₂ Nanoparticles through Sulfate Route

“…TiO2 with unique properties makes it a precious commodity in industries such as paints and coatings, polymers, cosmetics, and photocatalysis [2]- [4]. Because of its capacity to efficiently convert light into energy, titanium dioxide is used as a component in dye-sensitized solar cells in electronics [5].…”
