Abstract

SnO2–CuO mixture phase has been prepared by pyrolysis of an aerosol produced by ultrahigh frequency of different precursor solutions. As-received samples were annealed in different conditions to study the influence of the temperature on the microstructure. Scanning electron microscopy 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.
