With the continuous advancement of industrialization, the vigorous development of machinery, the petrochemical industry, automobiles, and the building materials industry has brought about increasing industrial exhaust emissions. Enormous typical atmospheric pollutants (such as sulfur compounds, NOx, organic gas pollutants, etc.) are difficult to decompose, which brings great challenges to environmental protection. Adsorption is an important means to remove atmospheric pollutants: solid particle dust and some organic gas pollutants can be directly removed by physical adsorption, and sulfides and nitrous oxides can be removed by chemical adsorption. Compared with other treatment technologies for air pollutants, the adsorption method is cleaner, safer, and more efficient.

This Special Issue aims to publish research and engineering applications related to adsorption in the field of gas pollutant control. Topics of interest include efficient physicochemical adsorption of typical atmospheric pollutants (such as solid particulate dust, VOCs, sulfides, and NOx), adsorption devices and processes, modification and regeneration of adsorbents, and adsorption kinetics and thermodynamics. Recently, in the field of adsorption gas pollution control, the modification and regeneration of the adsorbent with the superior economy (active carbon, ZSM-5, activated alumina, silica gel, etc.), micro-regulation of surface characteristics, secondary pollution of the adsorption process, and development of adsorbents with high stability and selectivity have attracted wide attention. Original research and review articles are welcome.

Potential topics include but are not limited to the following:

• Modified active carbon (regulating surface functional groups, load metals, etc.)
• Development of high-efficiency and stable new organic polymer adsorbents
• Removal of SO2, NOx, heavy metals, and VOCs by chemical adsorption
• Adsorption material regeneration and secondary pollution control
• Study on synergistic mechanisms of adsorption and catalysis
