摘      要：The nanocomposites of ZnO-SnO2and In2O3-SnO2were prepared by wet chemical co-precipitation method as a novel semiconductor gas sensing materials for the detection of environmentally toxic *** preparation parameters were critical towards the grain size and crystallinity of the obtained *** results showed that these nanocomposites exhibited high sensitivity and selectivity for the detection of CO and NOx,and the sensitivity depended on the composition of the composite,calcination temperature and operating *** gas sensing properties of the sensors were further improved through incorporation of dopants and surface *** gas sensing mechanism was also discussed by X-ray photoelectron spectroscopic （XPS） and temperature-programmed desorption （TPD） studies.
