基于低温等离子体辅助催化发光的乙烯传感器
A Low Temperature Plasma-assisted CataluminescenceSensor for Detection of Ethylene
摘要
Abstract
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, the sensor showed good selectivity and stability in ethylene detection.Due to the absence of the heating element, the present sensor was simple, rapid, 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.关键词
