Hydrophobic Carbon with Abundant Defects and Nitrogen Enrichment Effectively Enhances Adsorption of Styrene: Experiments and DFT Calculations
/g and the highest nitrogen content (5.82%). Even at 50% relative humidity, PNC-280 was still able to retain 80% of its styrene adsorption capacity (1329 mg/g). Density functional theory (DFT) calculations indicate that the adsorption energy of N-6 for styrene is -18.58 kJ/mol, while that for water is -5.43 kJ/mol, thereby reducing competition from water vapor and simultaneously increasing the affinity for styrene. This study offers a solution for enhancing the adsorption of styrene under humid conditions.
