Received Date:  2018-10-03

Fund Project:  This work was supported by the National Natural Science Foundation of China (Nos. 21775167, 21475153, 21575167, 21675178) and the Natural Science Foundation of Guangdong Province, China (No. 2016A030313358).

制备了TiO2-Y2O3纳米复合材料,并研究了环氧丙烷在其表面产生的催化发光现象,基于此,研制了环氧丙烷催化发光传感器。此传感器对丙酮、乙醛、苯等常见的挥发性有机物没有响应,显示出良好的选择性。对复合物的不同氧化物比例及烧结温度进行优化,得到TiO2与Y2O3质量比为1:3、烧结温度为500℃时,催化材料性能最佳。在最优实验条件下,即197℃、波长490 nm及载气流速0.3 L/min时,催化化学发光强度与环氧丙烷浓度在4.5~1375 mg/L范围内呈现良好的线性关系,检出限(3σ)为1.25 mg/L。此传感器具有灵敏快速、操作简便等优点,采用此传感器实时监测熏蒸谷物中环氧丙烷残留量,结果与气相色谱法吻合,相对偏差为2.7%~4.9%,显示出此传感器良好的性能。对环氧丙烷催化氧化的机理进行了初步探讨。
