摘要：In this study, the physicochemical properties of activated carbons (ACs) prepared from penicillin mycelial residues (PMR) and melamine was characterized, and the adsorption behavior of N-doped ACs for dichloromethane (DCM) and chlorobenzene (CLB) at humidity environment was explored. The results showed that the addition of melamine increased the nitrogen content in the precursors, enhanced the vibration intensity of amino groups, and reduced the thermal stability of the precursors. AC290-PM-1/5 showed the higher specific surface area (2009.91 m2/g) and micropore area (1591.84 m2/g), which gradually decreased with the increase of N-doped ratio. The increase of N-doped ratio changed the micromorphology of ACs, reduced the degree of graphitization, improved the amino functional groups. At the relative humidity of RH50%, AC290-PM-1/5 showed highest adsorption capacity of DCM and CLB (141.67 mg/g and 490.11 mg/g, respectively). In addition, density functional theory (DFT) was used to explain the effect of different forms of N on adsorption. According to adsorption performance, it was suggested that improving the hydrophobic performance of ACs on the premise of ensuring superior specific surface area and micropore area was conducive to improving the selective adsorption of ACs to VOCs in humidity environment.
