Dye-sensitized solar cells (DSSCs) based on hierarchical rutile TiO(2) flower clusters prepared by a facile, one-pot hydrothermal process exhibit a high efficiency. Complex yet appealing rutile TiO(2) flower films are, for the first time, directly hydrothermally grown on a transparent conducting fluorine-doped tin oxide (FTO) substrate. The thickness and density of as-grown flower clusters ca...

Carbon-based TiO₂ composites have many advantages as photocatalysts. However, they suffer from low light efficiency due to the low contrast of TiO₂ with carbon. We synthesized a novel type of anatase-type TiO₂-C hybrid aerogel by a one-pot sol-gel method, which shows a photocatalytic activity for methylene degradation up to 4.23 times that of P25, a commercial photocatalyst from Degussa Inc. Th...

Lines of TiSi, were written on Si(100) substrates by using a focused Ar+-laser. The reaction gas mixture consisted of TiCl, and H, and the substrate was used a s the silicon source. The laser deposited TiSi, lines were examined as a function of the deposition parameters. Especially the initial reactions have been studied b varying the the writing speed in a wide range. The C-54 phase of TiSi, w...

Phosphonylated azaheterocycles are an important class of compounds with high biological potential as conformationally restricted bioisosteres of amino acids. Therefore, it is of interest to synthesize conformationally constrained amino phosphonates. We wanted to investigate possible routes via ring opening of alpha-amino phosphonates with an oxanorbornene skeleton, as these can be synthesized w...

Abstract Single crystal anatase TiO 2 nanosheets (TNS) were grown on a fluorine‐doped tin oxide (FTO) substrate and then modified via multiple TiCl 4 treatments to produce hierarchical structure. This high surface area structure was decorated with CdS (as visible light absorber) using SILAR treatments. The resulting photoanodes provide greatly enhanced photoelectrochemical H generation capabili...

A nanocomposite of titanium dioxide (TiO(2)) and polyaniline (PANi) was synthesized by in-situ chemical polymerization using aniline (ANi) monomer and TiCl(4) as precursors. SEM pictures show that the nanocomposite was created in the form of long PANi chains decorated with TiO(2) nanoparticles. FTIR, Raman and UV-Vis spectra reveal that the PANi component undergoes an electronic structure modif...

A range of unsubstituted (1,2) and 6-substituted (3-5) ortho-phenoxy-imine ligands have been prepared and converted to their silyl ether derivatives (6-10). Reaction of silyl ethers with TiCl(4)(thf)(2) in the case of the unsubstituted species yields bis-ligated complexes while the substituted species react cleanly to yield complexes of the form [Ti(O^NR)Cl(3)(thf)]. In most cases the complexes...

In this work, we describe a kinetically controlled crystallization process assisted by an oriented attachment (OA) mechanism based on a nonaqueous sol-gel synthetic method (specifically, the reaction of titanium(IV) chloride (TiCl(4)) with n-octanol) to prepare re-crystallized anatase TiO(2) mesocrystals (single crystal). The kinetics study revealed a multi-step and hierarchical process control...
