Abstract

Abstract: SnO₂/ZnO composites were synthesized by a facile hydrothermal method using SnCl₄·5H₂O and Zn(AC)₂·2H₂O as the raw material and NaOH as the precipitant, which makes SnO₂ nanoparticles adhere to the surface of silkworm chrysalis-like ZnO. The structure and morphology of the obtained materials were characterized by XRD, TEM, HRTEM and BET. And the effects of temperature, ethanol concentration and other factors on the sensitivity were inverstigated. The results confirmed that the composite materials were SnO₂ nanoparticles and silkworm chrysalis-like ZnO. The SnO₂ nanoparticles were distributed on the surface of ZnO. The SnO₂/ZnO composite exhibited good gas-sensing properties, and the sensitivity of the sensor to 200μL/L ethanol was 39.68 at the optimum operating temperature (240℃), which were almost double of that of the individual SnO₂(24.53) and ZnO sensor(17.8).

Key words: SnO₂/ZnO, particles, hydrothermal, composites, gas-sensing properties, selectivity

摘要： 以五水四氯化锡（SnCl₄·5H₂O）和乙酸锌[Zn （AC）₂·2H₂O]为原料，氢氧化钠（NaOH）为沉淀剂，采用简单的水热法，使二氧化锡（SnO₂）纳米颗粒锚定在蚕蛹状氧化锌（ZnO）表面，一步成功合成了二氧化锡/氧化锌（SnO₂/ZnO）复合材料。采用X射线衍射仪（XRD）、透射电镜（TEM）、高分辨透射电镜（HRTEM）和氮气吸附脱附仪（BET）对材料的结构和形貌进行了表征，研究并讨论了温度、乙醇浓度等因素对SnO₂、ZnO及SnO₂/ZnO复合材料气敏性能的影响。结果表明，所得样品为SnO₂纳米颗粒与蚕蛹状ZnO的复合物，SnO₂纳米颗粒较均匀地负载在ZnO表面。SnO₂/ZnO复合材料气敏元件在最佳工作温度为240℃时，对200μL/L乙醇的灵敏度达到39.68，与SnO₂（24.53）及ZnO （17.8）相比，气敏性能得到了很大的提高。
