Antibiotics (ANTs) deep purification using pyrolytic carbons (PyCs) has been demonstrated as a promising strategy. Since PyCs structural modification is the key to enhancing their capacity, underlying mechanisms need be further clarified. Here, three nitrogen-doped porous with solid-sphere, hollow-sphere, and bowl-shape were prepared soft-template-KHCO3 copyrolysis method. The bowl-shaped bNPyC, BET/micropore surface area of 2072.79/1415.9 cm2/g, showed highest adsorption capacity for sulfamethoxazole (SMZ, Qfitted, max = 5.44) ciprofloxacin (CIP, 3.23 mmol/g) rapid equilibrium. Despite slight N doping (0.69%), SMZ/CIP on bNPyC improved significantly 48.6%/64.2%. Additionally, outperformed other reported in Q/N exposure value. exhibited excellent performance ANTs across wide pH range 2–10, particularly CIP. interactions semiquantitatively identified by probe competition experiments confirmed spectra characterizations density functional theory calculations. Mechanism analysis revealed that facilitates not only π–π EDA but also charge-assisted H-bond between ANTs. anti-interference properties, recyclability, universality removal demonstrated. These findings may guide design deepen our understanding structure–property mechanism ANT PyCs.
