Adsorption of Rhodamine B and Pb(II) from aqueous solution by MoS nanosheet modified biochar: Fabrication, performance, and mechanisms.

Mediated by polydopamine, MoS nanosheets were immobilized on the porous biochar derived from fungus residue, forming a novel biochar-based nanocomposite (MoS-PDA@FRC) for the removal of Rhodamine B(RhB) and Pb(II) from water. Utilizing MoS nanosheets with abundant active adsorption sites, MoS-PDA@FRC showed higher adsorption capacities than raw biochar, with 2.76 and 1.
