The synthetic route was developed, which does not require the activation that is frequently-used for active carbon materials. By manipulating their interaction, SDBS was deposited with CS in neutral and basic conditions. Subsequent calcination successfully has access to NSB. It features with hierarchical porous structure and abundant functional groups. The dually-doped NSB bears excellent adsorption performance towards chlortetracycline (CTC). The adsorption capacity reaches 101.3 mg g−1 within 4 h. It is 200% higher than that of N-doped biochar (NB) prepared by only CS. The renewable and cost-effective raw materials and simple preparation method would enable NSB to be a good candidate for remedying antibiotics in the environment.
