Adsorption performance of Congo red and malachite green in binary system using Co3O4 and Fe2O3 co-doped g-C3N4

Key Points

• The adsorption of Congo red and malachite green is significantly enhanced in a binary system with co-doped g-C3N4.
• Maximum adsorption capacity reaches 145 mg/g for Congo red and 160 mg/g for malachite green under optimal conditions.
• Using materials like Co3O4 and Fe2O3 improves the performance of g-C3N4 as an adsorbent in wastewater treatment applications.
• This approach may provide an effective solution for removing dyes from industrial wastewater, enhancing pollution control.
