摘要:
以五水四氯化锡和六水合氯化镍为原料，四乙基氢氧化铵为沉淀剂，用水热法制备出镍掺杂二氧化锡纳米材料. 通过X射线衍射、比表面及孔径分析仪对制备的纳米材料进行表征. 结果表明：制备的镍掺杂二氧化锡材料为纳米材料，晶粒尺寸小于10 nm. 镍的掺杂量为10 %（摩尔分数）的二氧化锡气敏元件对甲苯的气敏性能最好，在最佳工作温度400 ℃下，其对气体体积分数为1×10-4甲苯气体的灵敏度为18.05，与纯二氧化锡气敏元件的灵敏度（8.71）相比，提高了1倍.
Abstract:
Nickel doped tin oxide nanomaterials were synthesized by hydrothermal method using stannic chloride pentahydrate and nickel chloride hexahydrate as raw materials and tetraethyl ammonium hydroxide as precipitant. The obtained nanomaterials were charactered by X-ray diffractometer and Brunauer Emmett Teller N2 adsorption-desorption analyzer. The result showed that the nickel doped tin oxide materials are nanocrystals with the grain sizes less than 10 nm. The tin oxide sensor with 10 mol% nickel doped concentration exhibites good gas-sensing properties, and the sensitivity of the sensor to 1×10-4 toluene （volume ratio） is 18.05 at the optimum operating temperature （400 ℃）, which almost doubles that of the pure tin oxide sensor （8.71）.
