Volatile organic compounds (VOCs) are air pollutants that pose a major concern, and novel treatment technologies must be continuously explored and developed. In this study, microwave-induced metal discharge was applied to investigate the destruction of acetone as a representative model VOC compound. Results revealed that metal discharge intensity largely depended on microwave output power and the number of metal strips. Microwave metal discharge exerted the distinct combined effects of intense heat, strong light, and plasma. In the case of MW without metal discharge, the decrease in acetone at 200 ppm was remarkably limited (approximately 5.5% (mol/mol)). By contrast, in the case of microwave-induced metal discharge, a considerably high destruction efficiency of up to 65% (mol/mol) was obtained at low concentrations. This finding highlights the potential of microwave-induced discharge for VOC removal. Initial assessment indicated that energy consumption can be acceptable.
挥发性有机化合物（VOCs）是一种主要的空气污染物，必须不断探索和开发新的处理技术。在这项研究中，微波诱导金属放电被应用于研究作为代表性模型 VOC 化合物的丙酮的破坏。结果表明，金属放电强度在很大程度上取决于微波输出功率和金属条的数量。微波金属放电产生了强烈的热、强光和等离子体的综合效应。在没有金属放电的情况下，200ppm 丙酮的减少量非常有限（约 5.5%（摩尔/摩尔））。相比之下，在微波诱导金属放电的情况下，在低浓度下可获得高达 65%（摩尔/摩尔）的相当高的破坏效率。这一发现突出了微波诱导放电去除 VOC 的潜力。初步评估表明，能量消耗是可以接受的。
