Article Description

High N-doped hierarchical porous carbon (HNHPC) with ultrahigh BET surface area (S BET ) and pore volume (V pore ) has attracted great attention in capacitive deionization (CDI) due to the copious active sites. However, the traditional methods often adopt strong corrosive activators and fail to achieve high N-doping, which are harmful for its practical application. Herein, we develop a sustainable CO(NH 2 ) 2 -C 6 H 5 O 7 (NH 4 ) 3 -co-assisted C 6 H 5 K 3 O 7 (U-A-co-assisted P) self-activation strategy to prepare ultrahigh S BET and V pore HNHPCs for CDI desalination. Compared to the single P self-activation and U/A-assisted P self-activation, HNHPC PUA acquired via U-A-co-assisted P self-activation possesses ultrahigh S BET (3280.16 m 2 /g), splendid V pore (2.49 cm 3 /g), high V meso /V pore (57.83%) and high N-doping (6.40%). Its small hierarchical porous carbon nanogranlue structure helps to expose more accessible S BET and extra active sites, accelerating the ions insertion and extraction from the micropores. The resultant HNHPC PUA delivers a high specific capacitance of 203.9F/g. In the assembled CDI setup, HNHPC PUA exhibits a superior salt adsorption capacity (SAC) of 24.86 mg/g, a rapid salt adsorption rate (SAR) of 8.29 mg/g/min and reaches 88.7% SAC retention after 50 cycles in 500 mg/L NaCl at 1.2 V, suggesting good application potential. Overall, this work provides new insight into rapidly preparing ultrahigh S BET and V pore HNHPCs for energy and environmental applications.
