Fabrication And Characterization

Various KNbO3 powders have been derived from sol-gel process by using different preparation and heating conditions. KNbO3 powder derived from ethanol solution and fabricated at 800oC was most suitable as the raw material of KNbO3 bulk ceramics, because of the small grain size of about 250 nm and its homogeneous size distribution.

TiO2 nanoparticles (TiO2) and Ag-doped TiO2 nanocomposites (Ag-TiO2) were synthesized by the Sol-Gel process using titanium tetra isopropoxide as TiO2 and AgNO3 as Ag precursors, respectively. The synthesized nanocomposites were characterized by XRD, SEM, TEM, FT-IR, and UV­-Visible analysis. The XRD results show that Ag doping increases the grain size from 22 nm to 36 nm. From the UV-Visible spectra, the redshift in absorbance was observed, which indicates the increase in grain size and it reduces the bandgap. The TEM analysis shows that all the particles are exhibited in the nanometer range. The synthesized nanoparticles show good photocatalytic activity, and they decompose the methyl orange dye within 5 hours.

Ferrocene (Fc) is an organometallic compound of sandwich structure. As the anticancer and excellent electrical activities, ferrocene and its derivatives have many applications in electrochemical monitoring [1-3]. Hydrogen peroxide (HP), with strong permeability and oxidation properties, is the product of many peroxidase catalyzed reaction, and it is widely used in medical and cosmetic fields, even for food bleaching by some illegal merchants which may cause healthy problem. In this study, the polyelectrolyte multilayer films containing ferrocene-derived polymer assembling by sol-gel process [4] was introduced to HP determination as a sensor.
