, dihydroxy, and phosphonic acid on pyridine ligands have been used as dyes for photovoltaic applications [ 1 – 9 ]. In these complexes, the anchoring groups are responsible for immobilizing the dye on the nanocrystalline TiO 2 surface. While their structural

, Ltd.) was hydrolyzed with H 2 O in n -butanol, and then the obtained gel was dried at 130 °C overnight. Finally, the dried gel was calcined at 500 °C in air. The sol–gel method was also employed for the preparation of TiO 2 –Al 2 O 3 (TiO 2 = 80 wt
-treated samples (see Fig. 6 ) evidenced the presence of oxides, namely Ti 6 O and TiO 2 (rutile), in the TiH 2 powder. Weak oxygen traces are already in the non-treated samples. The original Ti-hydride containing 1.924H/Ti has been identified as tetragonal
urges the research interest on nitrocyclohexane hydrogenation [ 10 , 11 ]. Serna et al. [ 12 ] have prepared a decorated Pt/TiO 2 catalyst doped with sodium cation, which could catalyze the nitrocyclohexane hydrogenation to cyclohexanone oxime under 4
important to mention that the molecular dynamics simulation of Hoang [ 23 ] predicts that the glass transition temperature increases with the decrease in size of the TiO 2 nanoparticles which seems unphysical as well as contradicts the general nature of
) showed the presence of the following oxidation products: Fe 2 O 3 , Ni x Fe 3− x O 4 and TiO 2 (rutile). Fig. 9 X-Ray diffraction pattern of the powder containing 10 wt.% of nc-TiC 0.85 and 90 wt.% of 316L steel

technique (DST) for the separation of various steps in a surface catalytic reaction. She used this technique for the study of several reactions of single oxides as Al 2 O 3 , SnO 2 , CeO 2 , TiO 2 , etc. She was also interested in nanomaterials science
pyridine ligands serve to immobilize the dye on the nanocrystalline TiO 2 surface. Structural properties and applications of ruthenium-(II) polypyridine complexes have been studied extensively but thermal properties of these compounds are rarely
