| 摘 要： | 以SnCl2·2H2O为原料,采用溶剂热法,分别在体积分数为95%的乙醇及95%乙醇–油酸体系中制备了单分散的SnO2纳米粉。利用XRD和TEM等手段,对产物进行了表征,并对其气敏性能进行了测定。结果表明:在95%乙醇–油酸体系中制备的SnO2,粒径约为15nm,在4V的工作电压下,对体积分数为100×10–6的氯气灵敏度为370,响应–恢复时间仅为1s。

| Abstract: | SnO2 nanopowder was prepared by solvothermal method using SnCl2·2H2O as raw material in different solvents. It was characterized by means of powder X-ray diffraction,transmission electron microscope and gas sensing properties measurements. The results show that the sizes of SnO2 nanopowder prepared in alcohol (95 %) and oleic acid mixed solvent are less than 15 nm. Its sensitivity is 370 to 100×10-6 (volume fraction) chlorine at working voltage 4 V,and response-recovery time is only one second. |
