本文通过水热法合成氧化锡/硫化钼复合材料。扫描电子显微镜图像显示该复合物表现出层状结构。安培响应曲线表明该复合物对亚硝酸盐的氧化有着极好的电催化活性。测量电流的响应结果显示氧化锡/硫化钼改性的玻碳电极可用于检测亚硝酸根浓度的线性范围为0.98~5160μM。

Tin oxide/molybdenum sulfide composite material was prepared by hydrothermal method. It was characterized by scanning electron microscopy （SEM）. The amperometric response curves indicated that SnO2-MoS2 has excellent electrocatalytic activity for the oxidation of nitrite. The curves show the SnO2-MoS2/CJCE can be used to determine nitrite concentration in a wide linear range of 0.98 μM and 5160 μM.
