摘　　要：将水热法制备的ZnS纳米球500℃保温2h制备出由ZnS、ZnO纳米片组装的多孔微球。利用扫描电子显微镜、X射线衍射仪和透射电子显微镜对样品的形貌和结构进行了表征。测试多孔ZnS/ZnO微球传感器对不同浓度的乙醇、三乙胺和丙酮的传感性能,并讨论其增强的响应机理。Porous microspheres assembled with ZnS and ZnO nanosheets were synthesized by annealing ZnS nano- spheres via a hydrothermal reaction at 500~C for 2h. The morphology and microstructure of samples were characterized by scanning electron microscope （SEM）, X-ray diffractometer （XRD） and transmission electron microscope （TEM）. The gas sensing properties of microspheres sensors towarded ethanol, triethylamine and acetone with different concentration were tested. The mechanism for the enhancement of gas-sensing properties of microspheres was also discussed.
