NO和NO_2是典型的大气污染物;作为被吸附物,它们具有不同的性质。NO的临界温度为180K,在室温下处于超临界状态;而NO_2是一种可凝气体,因它的沸点为294K,且具有二聚作用。因此,只有极少数微孔固体才对NO有效吸附。分散的过渡金属氧化物的活性炭纤维(ACF)利用微孔填充的化学吸附能吸附大量的NO。在氧化铁为分散体时,以α-FeOOH和α-Fe_2O_3为分散体的ACF与其它铁的氧化物或氢 NO and NO 2 are typical atmospheric pollutants; as adsorbates, they have different properties. NO has a critical temperature of 180 K and is in a supercritical state at room temperature. NO 2 is a condensable gas because of its boiling point of 294 K with dimerization. Therefore, only a very small number of microporous solid adsorbed NO effectively. Dispersed transition metal oxide activated carbon fibers (ACF) using microporous chemisorption can adsorb large amounts of NO. In the case of iron oxide as a dispersion, ACF dispersed with α-FeOOH and α-Fe 2 O 3 and oxides of other iron or hydrogen
