“…The CO2 philicity of the polymeric network has tremendously increased from previously reported modified polycarbazole and polytriphenylamine. CO2 uptakes of these two materials are also very comparable with previously best reported COFs [38,39], MOFs [40,41], N-doped microporous carbons [42,43], hypercrosslinked porous polymers [44][45][46] , etc. The high density of basic nitrogen sites of triazine present in the polymer network which interact with ewis acidic CO2 molecules via dipole quadrapole interaction, are responsible for huge CO2 uptake [47].…”

supplimentary information (ESI) available: BET specific surface area plot, thermal stability of SB-TRZ-CRZ and SB-TRZ-TPA, synthetic procedures, 13 C and 1 H NMR spectra. AbstractTargeted synthesis of microporous adsorbents for CO2 capture and storage is very challenging in the context of remediation from green house gases. Herein we report two novel N-rich microporous networks SB-TRZ-CRZ and SB-TRZ-TPA by extensive incorporation of triazine containing tripodal moiety in the porous polymer framework. These materials showed excellent CO2 storage capacities: SB-TRZ-CRZ displayed the CO2 uptake capacity of 25.5 wt% upto 1 bar at 273 K and SB-TRZ-TPA gave that of 16 wt% under identical conditions. The substantial dipole quadruple interaction between network (polar triazine) and CO2 boosts the selectivity for CO2/N2. SB-TRZ-CRZ has this CO2/N2 selectivity ratio of 377, whereas for SB-TRZ-TPA it was 97. Compared to other porous polymers, these materials are very cost effective, scalable and very promising material for clean energy application and environmental issues.2

Polystyrene is cross-linked to generate micropores for sorption applications. Herein, we report, hypercross-linking of polystyrene in the presence of Friedel-Crafts catalyst, FeCl 3 without a cross-linker. For comparison, polystyrene was also hypercross-linked with a cross-linker, dimethoxy methane with the same catalyst. The cross-linking and de-hydrogenation of cross-links to quinonoid formation were confirmed by FT-IR and 13 C-NMR techniques. The hyper cross-linked polymers (HCPs) were also characterized by TGA, DRS-UV, SEM, Raman, BET and CO 2 sorption techniques. All the HCPs showed a maximum of 5 weight % CO 2 sorption at 25 o C and 1 atm. The same polymers could also be applied for the sorption of other air pollutants.

“…Recently some applications on bean dreg have been reported, such as activated carbon [30], supercapacitor [31]，lithium-sulfur battery [32], however its application in anode for lithium-ion battery has hardly been found. Herein, we report a simple and effective strategy in preparing LIB anode material from bean dregs with pyrolysis treatment at different temperatures and further treatment via graphitization and chemical activation.…”

The KOH-activated sample demonstrated enhanced electrochemical performance due to its high surface area and abundant mesoporous structure. Bean-dreg-derived carbon materials used as superior anode material for lithium-ion batteries AbstractThe structures of modified carbons from bean dregs were regulated via graphitization treatment and chemical activation. The microstructure and electrochemical performance were studied using X-ray diffraction, Raman spectrometer, SEM and TEM techniques. The electrochemical performance was investigated using electrochemical methods. After heat-treatment at 2800 O C, the obtained BDC-2800 possessed a high degree of graphitization and showed an outstanding cycling performance, delivering capacity decay from 423 to 396 mAh g -1 at 0.1 C after 100 cycles. The chemical-treated carbons also demonstrated enhanced electrochemical performance, especially for the KOH-treated sample. The BDC-K displayed superior specific charge capacity of 801 mAh g -1 at 0.1 C, and showed an impressive rate capability of 643 mAh g -1 at 1 C. In addition, this sample delivered capacity retention of 94%after 500 cycles at 1 C. This good electrochemical performance was mainly due to its high surface area and abundant mesoporous structure.
