In this paper, we investigate the effect of annealing temperature on structural, optical, and photocatalytic properties of nanostructured ZnTiO3 thin films deposited on Si substrates. ZnTiO3 coatings were prepared by consecutive sol-gel method and further deposited on Si substrates by spin-coating. The obtained films were annealed at three various temperatures namely 700°C, 800°C, and 900°C. X-ray diffraction analysis shows that the crystallite size of the films grows from 100 to 125 nm as the annealing temperature increases from 700 to 900°C. At the same time, the roughness increases from 232 to 289 nm and the band gap dwindles from 3.73 to 3.05 eV. ZnTiO3 coatings annealed at 700°C exhibits the highest photodegradation rate about 74 % to catalyze the degradation of the Methylene Blue aqueous solution. We demonstrate that this high photocatalytic activity is attributed to the structural and optical properties of prepared samples.

This work reports on correlation between structural and morphological properties of ZnTiO3/ porous silicon (PS). The PS were elaborated by electrochemical anodization from the single-crystal p-type silicon wafer. Nanocrystalline ZnTiO3 thin films have been prepared on PS using sol-gel spin coating technique. The deposited films were annealed in air at 800 °C for two hours. The structural, and morphological properties of the films were studied for different number of layers. X-ray diffraction spectra confirms that ZnTiO3 films were hexagonal phase and the crystallite size of ZnTiO3 films increased from 120.56 nm to 125.45nm when the number of layers increase from 4 to 8 layers. SEM image shows approximate semi-spherical particles with a little agglomeration for all samples. The morphologies changed and the average grain size changed and increase from 81nm to 131nm.

Nano-sized La 0.5 Ca 0.5 CoO 3 perovskite, which was produced via the sol-gel method, was an efficient heterogeneous catalyst in combination with NaBH 4 for the rapid chemoselective reduction of aryl nitriles to bis-(benzyl)amines at 40 ºC in good to excellent yields. The physico-chemical properties of the catalyst were characterized by means of differential thermal analysis (DTA), thermogravimetric analysis (TGA), X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDX) and particle size distributions images. The results show that nanoparticles have regular shapes with well-defined crystal faces with an average size of 30 nm.
