Abstract (en)

[origin: WO9925961A2] Nitric oxide (NO) and nitrogen dioxide (NO2) are removed from air by an adsorbent including a combination of a support and an alkali material. The support is a mixture including manganese dioxide (MnO2) and copper oxide (CuO). The alkali material may be, for example, potassium carbonate (K2CO3) or potassium hydroxide (KOH). The adsorbent allows efficient NOx removal occurs at temperatures below 100 DEG C.
