采用一步水热法制备不同浓度Ni掺杂SnO2材料，并对所制备材料进行XRD、XPS、SEM表征，结果表明成功制备了纯SnO2和不同浓度Ni掺杂SnO2的纳米材料。然后将材料制作为气体传感器进行气敏测试，结果表明1%Ni掺杂SnO2的气体传感器性能最佳，在200℃时对50 ppm乙醇的响应为91，比纯SnO2气体传感器最佳工作温度降低20℃，响应提升3.1倍
Abstract：Here, Ni-doped SnO2 materials are perapred by one-step hydrothermal. Through the XRD, XPS and SEM surface features, the results indicate the pure SnO2 and different Ni-doped SnO2 are successful preparation.Then, the material is then fabricated as a gas sensor for gas-sensitive testing. For the gas sensor with 1% Ni-doped SnO2, the optimal operating temperature is 200 ℃, the response reaches 91 to 50 ppm ethanol. The optimal operating temperature is 20 ℃ lower than the pure SnO2 gas sensor, and the response is increased by 2.1 times.
