“…At this juncture, the plasma supported catalysts/adsorbents showed improved results in the gas treatment at laboratory environment [21,22]. This improved result has come from the synergetic effect of plasma and the catalysts/adsorbents [23][24][25][26][27][28][29][30][31][32][33]. The additional expenditure on plasma, though escalates the cost of gas treatment, the benefits due to high pollutant removal efficiency outweigh the cost factor.…”

Solid waste in association with plasma was explored as an alternate to commercial catalyst/adsorbents. We have demonstrated reuse of foundry sand and red mud wastes for adsorption of gaseous pollutant from plasma treated diesel exhaust. A novel dielectric barrier discharge reactor with dual metal film is designed to explore the oxidation potential of surface discharge plasma effect onto the exhaust. The metal film was subjected to high voltage pulse/AC energization to assess the effect of plasma in oxidising NO to NO2. A separate reactor filled with industry wastes was cascaded with plasma reactor to test its efficacy in NO2 adsorption. It was observed that some amount of NO was also reduced owing to some visible light-enabled photocatalytic activity. About 85 % NOx (oxides of nitrogen) reduction was observed with red mud waste compared to half of that with foundry sand.
