One-Pot Synthesis of N-Rich Porous Carbon for Efficient CO₂ Adsorption Performance.

ABSTRACT: N-enriched porous carbons have played an important part in CO₂ adsorption application thanks to their abundant porosity, high stability and tailorable surface properties while still suffering from a non-efficient and high-cost synthesis method. Herein, a series of N-doped porous carbons were prepared by a facile one-pot KOH activating strategy from commercial urea formaldehyde resin (UF). The textural properties and nitrogen content of the N-doped carbons were carefully controlled by the activating temperature and KOH/UF mass ratios. As-prepared N-doped carbons show 3D block-shaped morphology, the BET surface area of up to 980 m²/g together with a pore volume of 0.52 cm³/g and N content of 23.51 wt%. The optimal adsorbent (UFK-600-0.2) presents a high CO
