Enhanced adsorption and desorption of VOCs vapor on novel micro-mesoporous polymeric adsorbents

[Display omitted] •Polymeric adsorbents with well-developed micro-mesopore were prepared.•High BJH surface area can enhance adsorption of medium–high concentration of VOCs.•Mesopores near to macropores make very limited contribution to VOCs adsorption.•Mesopore can effectively improve the desorption efficiency. To enhance adsorption and desorption efficiency of volatile organic compounds from gas streams, we synthesized a series of well-developed micro-mesoporous hypercrosslinked polymeric adsorbents (MM-1, MM-2, and MM-3). The adsorption and desorption performance of dichloromethane and 2-butanone on newly synthesized adsorbents was investigated and compared with commercial micropore-dominated hypercrosslinked polymeric adsorbent (JT-001). The contributions of micropore and mesopore to adsorption and desorption of dichloromethane and 2-butanone on polymeric adsorbents were well elucidated. Consequently, the adsorbent MM-3 had been sorted out with high BET surface area (1606m2/g), large micropore and mesopore volumes (0.562mL/g and 1.046mL/g, respectively). The MM-3 exhibited the similar adsorption capacities with JT-001 for dichloromethane and 2-butanone at regions of p/p0
