首次提出了一种基于纳米材料Y（2）O（3）、γ-Al（2）O（3）和ZrO（2）的催化发光（CTL）传感器阵列，用于二甲苯异构体的分子识别和定量分析。在优化条件下，CTL强度与二甲苯异构体浓度的线性范围为86.70-8670.00 mg m（-3）。使用传感器阵列代替单个传感器为识别类似化合物的过程提供了一种新的策略，在环境和工业监测中应该有光明的未来。
A facile and effective sensor array consisting of three cataluminescence (CTL) sensors based on nanomaterial Y(2)O(3), γ-Al(2)O(3) and ZrO(2) as probes was firstly proposed for the molecular recognition and quantitative analysis of xylene isomers. Under the optimized conditions, the linear range of CTL intensity versus concentration of xylene isomers was 86.70-8670.00 mg m(-3). The use of a sensor array instead of a single sensor has provided a novel strategy for the process of identifying similar chemical compounds, which should have a bright future in environmental and industrial monitoring.
