- Using radicalized NOₓ derivatives supported on metal oxideson September 17, 2021 at 2:18 pm
NOX (X=1 or 2) emitted from stationery/mobile sources are conventionally deemed as notorious, anthropogenic precursors of ultrafine particulate matters (PM2.5) because NOX can undergo a series of SO2-assisted photochemical transformative stages to finally evolve PM2.5 functioning as an air pollutant. Recently, a research group in South Korea rectifies the general notion of NOX (vide supra) by proposing an interesting means to exploit NOX in creative fashion.
