A one-step recycling strategy of MgO template was employed to synthesize porous carbon materials(PCMs)with high specific surface area,hierarchical pore structure and nitrogen-oxygen doping species using tar residue derived from the production of m-phenylenediamine as a carbon precursor.The PCMs were utilized for the adsorption removal of PNP in water.The structural and physicochemical properties of the PCMs were investigated by SEM,N2 adsorption-desorption test,elemental analysis and other techniques.Among the PCMs,HPC-1 exhibited a high static adsorption capacity of 445 mg/g for PNP and a rapid adsorption performance.Moreover,HPC-1 demonstrated a satisfactory dynamic adsorption performance for PNP and showed a promising potential for practical application.
