Synthesis and CO2 capture properties of mesoporous carbon nitride materials

Carbon dioxide adsorption on nitrogen enriched carbon adsorbents: Experimental, kinetics, isothermal and thermodynamic studies

“…The values for CO 2 adsorption capacity obtained for the prepared carbons are comparable to the values for previously reported materials under dynamic conditions [48,49]. Porous carbon adsorbents were synthesized from melamine-formaldehyde resin with K 2 CO 3 activation by Drage et al [23] and the adsorbent carbonized at 700 C showed CO 2 uptake of 0.86 mmol/g at 30 C. Arenillas et al [50] prepared carbon adsorbents from polyethylene terephthalate by using various nitrogen functionalities like acridine, carbazole and urea and chemical activation with KOH.…”

Covalent triazine polymers using a cyanuric chloride precursor via Friedel–Crafts reaction for CO2 adsorption/separation

“…This adsorption capacity of PCTP-1 was higher than that for the previously reported MOFs and POPs [38][39][40][41][42][43][44][45][46][47][48][49][50][51]. Notable examples include, Zn TEPO-1-3 (69.7-91.9 mg g -1 ) [46], carbon coating mesoporous carbon nitride (134.2 mg g -1 ) [47], and others [48][49][50][51]. The PCTP-1 network with a high loading of nitrogen atoms apparently interacts more effectively and strongly with CO 2 .…”

Novel P O codoped g-C3N4 with large specific surface area: Hydrothermal synthesis assisted by dissolution–precipitation process and their visible light activity under anoxic conditions

“…Two-dimensional (2D) graphitic carbon nitride (g-C 3 N 4 ), the most stable allotrope of covalent carbon nitride, has been widely used as a new metal-free visible light photocatalyst for organic pollutant degradation [2], water reduction and oxidation [3], CO 2 capture [4] and organic synthesis [5]. The tunable condensation degree and distinctive heptazine ring structure endow g-C 3 N 4 with good physicochemical stability as well as a fascinating electronic structure and medium band gap (2.7 eV) [6].…”
