摘要將等離子體的高活化性能與催化發(fā)光的傳感特性相結(jié)合,以成本低、合成簡單的堿土金屬納米Mg O為傳感材料,構(gòu)建了基于低溫等離子體輔助的催化發(fā)光傳感器,用于乙烯的快速檢測。由于等離子體具有高活化性能,本方法的檢測溫度遠(yuǎn)低于傳統(tǒng)的催化發(fā)光檢測法的常用溫度（300-500℃）甲苯檢測儀,無需加熱裝置,在室溫下實(shí)現(xiàn)了對乙烯快速、靈敏的檢測。室溫（25℃）下乙烯傳感器,對乙烯的檢出限為37 ng/m L（30 ppm）,線性范圍為112-4997 ng/m L（90-3998 ppm,R=0.97669）,傳感器具有良好的選擇性和重現(xiàn)性。此傳感器制備簡單、穩(wěn)定性高、低能耗、成本低,與傳統(tǒng)的氣體檢測方法相比具有良好的實(shí)用性和普適性,為開發(fā)性能優(yōu)異的新型催化發(fā)光傳感器提供了策略。Based on the plasma activation and the sensing ability of cataluminescence, a low temperature plasma-assisted cataluminescence sensor was developed for ethylene detection using the low-cost and abundant alkaline-earth oxides of MgO nanomaterials as the sensing materials. Taking advantage of the high activity of the plasma, the working temperature of this method was greatly decreased than that of traditional detection method （300-500℃） ,and the sensing of ethylene was realized at room temperature without any heating device. This ethylene cataluminescence sensor gave a linear range of 112-4997 ng/mL （90-3998 ppm,R = 0.97669） with a detection limit of 37 ng/mL （30 ppm）. Besides乙烯傳感器煤氣檢測儀, the sensor showed good selectivity and stability in ethylene detection. Due to the absence of the heating element, the present sensor was simple,rapid乙烯傳感器, low- cost, low energy-consumption and stable for ethylene sensing. This study improved the applicability of cataluminescence sensors and might promote the development of cataluminescence sensors.
