摘　　要：采用水热法,以酒石酸为形貌控制剂、以乙酸锌和尿素为原料,在载波片上制备了掺铝ZnO纳米片;采用XRD和SEM对其结构和形貌进行表征,以研究掺铝ZnO纳米片对丙酮、正丁醇、甲醇、乙醇、异丙醇、DMF 6种气体的气敏性能.结果表明,掺杂3%铝的ZnO材料晶粒尺寸最小,为花状和层状纳米片复合物,对丙酮的灵敏度较高.Al-doped ZnO nanosheets were prepared by the hydrothermal method,using tartaric acid as shape controling agent and zinc acetate and urea as doping source. The products were characterized by XRD and SEM. The gas sensing properties of as-prepared products to acetone,methanol,ethanol,isopropanol,n-butanol and DMF were also studied,respectively. The results showed that 3% Al-doped product had a smaller grain size and a multilayered nanosheet and flower morphology. The as-synthesized nanomaterials had good response to acetone.
