Nanostructure sensor films preparation by extraction-pyrolysis technique

We propose the extraction-pyrolysis technique for deposition of nanostructure films of oxide functional materials. The carboxylic acids have been used as extragent. The extraction process was realized by cation exchange mechanism. At the selective extraction the anions of inorganic salts and impurities of cations was not extracted in organic phase. Therefore, the application of extraction allows obtaining pure materials. In order to adjusting of metals concentration the extracts undergoes to analysis by atomic absorption spectroscopy. To determination the decomposition temperature TG-LTA investigations have been carried out. It was found that thermal decomposition of metal-carboxylates take place at 400 - 450 degC.
