Abstract
This paper reports the preparation and gas sensitivity properties of Zn1-xC dxFe2O4 to C2H2OH. Raw powders of Zn1-xCdxFe2O4 were obtained by a chemical co-precipitation and solid-state reaction method. The effects of the calci ning temperature on the phase constituents are characterized by X-ray diffr action (XRD). We investigated the influence of CdO on the conductance-tempe rature correlation, and gas sensing properties of ZnFe2O4. The results demo nstrated that CdO could improve the sensitivity, selectivity and response t ime of ZnFe2O4. (C) 2000 Elsevier Science S.A. All rights reserved.
