Activated Carbon for NO2 Removal
Nitrogen dioxide is a pervasive and aggressive urban pollutant that is difficult to capture using standard physical adsorbents due to its small molecular size and low polarity. Activated carbon with properly engineered surface chemistry provides a reliable and cost-effective solution for NO₂ abatement. When impregnated with ammonia as a reactive catalyst, the removal capacity of activated carbon increases by an order of magnitude compared to virgin carbon, making it the preferred media for gas-phase NO₂ control worldwide.
