Abstract
A micro-electric-NOx-converter based on volume treatment is proposed for the evaluation of NOx concentrations in air. It can electrically convert NOx mixture from variable mixing rates into a fixed-mixing rate of 25% NO2 and 75% NO using the corona discharge process with stable conversion efficiency and high throughput (space velocity = 6.3 × 104 h-1). The micro-electric-NO x-converter is based on a volume process. Applying high voltage to the electrodes of the micro-electric-NOx-converter generates a corona discharge. This discharge creates high-energy electrons, which collide with gas molecules. After these collisions, NO and O2 are broken into single atoms, and they are re-combined as a balanced form, NO2 in this case. The fabricated micro-electric-NOx-converter converted NO into NO2 at conversion efficiency of 25.63%, when 5.5 kV (the applied corona power = 0.196 W) was applied to the micro-electric-NOx- converter.
