The nanocomposite oxide (0.2TiO2–0.8SnO2) doped with Cd2+ powder have been prepared and characterized by XRD and their gas-sensing sensitivity were characterized using gas sensing measurement. Experimental results show that, bicomponent nano anatase TiO2 and rutile SnO2 particulate thick film doped with Cd2+ behaves with good sensitivity to formaldehyde gas of 200 ppm in the air, and the optimum sensing temperature was reduced from 360 °C to 320 °C compared with the undoped Cd2+ thick film. The gas sensing thick films doped with Cd2+ also show good selectivity to formaldehyde among benzene, toluene, xylene and ammonia as disturbed gas and could be effectively used as an indoor formaldehyde sensor.
