Valorization of N-doped biochar into Fe-Cu loaded carbon catalyst from electroplating wastewater: Structure regulation, adsorption performance, and catalytic properties.
The efficient removal and resource recovery of high-concentration heavy metals like Fe3⁺ and Cu2⁺ from electroplating wastewater remains a critical challenge. Herein, a sustainable closed-loop "adsorption-transformation-upcycling" strategy was proposed. Initially, a nitrogen-doped and CaO-activated pinewood biochar (N-...
