J. Roman et al., SYNTHESIS, STRUCTURE, AND GAS SENSITIVITY PROPERTIES OF SNO2-CUO MIXTURE PHASE OBTAINED BY PYROLYSIS OF AN AEROSOL, Journal of materials research, 12(2), 1997, pp. 560-565
SnO2-CuO mixture phase has been prepared by pyrolysis of an aerosol pr
oduced by ultrahigh frequency of different precursor solutions. As-rec
eived samples were annealed in different conditions to study the influ
ence of the temperature on the microstructure. Scanning electron micro
scopy showed that the samples consisted of hollow spherical particles
and rings, depending on the precursor solution utilized. The evolution
of conductance under both pure and polluted air is discussed.
