Abstract

Various gaseous pollutants, including CH₄, CO₂, volatile organic compounds (VOCs), SO₂, H₂S and NH₃ etc., have significantly contributed to the perceptible deterioration of air quality. This review focuses on the utilization of the typical porous carbon materials, such as activated carbon, carbon molecular sieve, activated carbon fiber, carbon nanotube, and graphene, etc. for air purification and pollution abatement. Their distinct physical and chemical properties were examined, which are crucial for the effectiveness and efficiency in adsorption processes. Furthermore, the enhancement of porous carbon materials' adsorption capabilities through physical activation (CO₂ and H₂O activation) and chemical modification (acid and alkali treatments and nitrogen doping) were also summarized. Additionally, the potential adsorption mechanisms for various pollutant gases were elaborated on different adsorbents. Finally, this review concludes the prevailing challenges and offers prospects on the future research endeavors in gaseous pollutants adsorption.
