The obtained catalysts were characterized by means of N2 sorption, XRD, Py–FTIR, FTIR, H2 chemisorption and TEM to determine the effect of the Pt precursor on their physicochemical properties. Catalytic performance of obtained catalysts was investigated in hydroisomerization of n-hexadecane.

The addition of the sac ligand resulted in the replacement of 1 and 2 chlorido ligands in [PtCl2(COD)] to yield 1 and 2, respectively. The structures of the complexes were determined by single crystal X-ray diffraction and showed a distorted square planar coordination geometry around platinum(II). COD acted as a π -donor ligand, while sac was N -coordinated in both complexes. The TG/DTA data indicated that both complexes were thermally stable up to 220°C in air and their thermal decompositions yielded Pt as a final product.

In this paper, nickel oxide thin films on the titanium substrate were prepared by the sol-gel dipcoating technique with the precursors NiSO4.7H2O and acetic acid. The obtained thin films have a good adhesion to the substrate. The electrochemical behaviors of the NiOxHy thin films were investigated in KOH 1 M solution by the voltammetry technique. The effect of addition of platinum, heating temperature and the dip coating number on the electrochemical behavior was also investigated. The thin films have high electrochemical properties at 270o C and at third dip coating.
