Abstract

A corona discharge based micro-electric-NOs-convener is proposed for (lie evaluation of total NOx in air. It can electrically convert NO x mixture from variable mixing rates into a fixed-mixing rate of 25% NO2 and 75% NO with stable conversion efficiency and high throughput (space velocity=6.3×104h-1). Applying high voltage to the electrodes of the micro-electric-NOx-converter generates a corona discharge. This discharge breaks KO into single atoms, and they arc re-combined as a balanced form, NO2 in this case. The fabricated micro-elecnic-NOx-converter converted NO into NO2 at conversion efficiency of 25.63 % at 5.5 kV (the applied corona power = 0.196 W).
