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… Show more

“…It can therefore be concluded from the overall results that the combination of textural features and suitable nitrogen functionality on carbon materials contributes to a positive effect on CO 2 uptake capacity than the effect of single textural properties. A similar phenomenon was previously reported in the literature [ 75 , 76 ].

“…It is interesting to underline that the highest CO 2 adsorption capabilities discovered in this inquiry are noticeably lower than those reported for some KOH-activated porous nanocarbons, as shown by earlier investigations, , However, they demonstrate equivalent or even greater adsorption values when compared with particular carbon materials and various other standard CO 2 adsorbents, including COFs, porous polymers, and MOFs . A complete comparison of the uptake of CO 2 among SDC carbons and other solid sorbents is presented in Table S2 of the Supporting Information.…”

“…As shown in Figure 3 a and Figure S1a , all samples had two broad diffraction peaks at 26.5° and 44.5°. By comparing with the standard card of graphite (JCPDS card No.01-0640), it can be observed that the peak at 26.5° corresponds to the (002) non-crystalline carbon of graphite, and the weak diffraction peak at 44.5° corresponds to (101), further indicating its degree of graphitization [ 37 ]. Therefore, these samples have a low degree of graphitization and exhibit a non-crystalline carbon structure, and this amorphous structure could promote the transport of charged ions [ 38 ].…”
