Descripción
Sumario:This paper deals with the functionalization of nanocrystalline SnO(2) with Cu(II) complexes with organic ligands, aimed at the improvement of sensor selectivity towards gas molecules. For the synthesis of metalorganic/SnO(2) hybrid material complexes of Cu(II) with phthalocyanine, porphyrinines, bipyridine and azadithiacrown etherwere used. The analysis of gas sensor properties showed the possibility of increasing the sensitivity and selectivity of hybrid materials in H(2)S detection due to the electron transfer from SnO(2) to an adsorbed organic molecule, which changes during the interaction between H(2)S and Cu(II) ions.
