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（VOC）是引起人们广泛关注的空气污染物，必须不断探索和开发新的处理技术。在这项研究中，微波诱导的金属放电被用于研究丙酮的破坏，该丙酮是代表性的挥发性有机化合物化合物。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热，强光和等离子的独特综合作用。在没有金属放电的MW的情况下，丙酮在200 ppm处的减少受到明显限制（约5.5％（mol / mol））。相反，在微波诱导的金属放电的情况下，在低浓度下获得了高达65％（mol / mol）的相当高的破坏效率。这一发现突出表明了微波诱导的放电具有去除VOC的潜力。初步评估表明，能耗是可以接受的。
