“…Thus, the NPCM with high specific surface area, well-defined microstructure and active surface nitrogen species (e.g., pyridinic, pyrrolic, quaternary and oxidized nitrogen) can be achieved for enhanced CO 2 capture performance. Both inorganic such as ammonium [20] and sodium amide [21] and organic nitrogen-containing materials such as urea [22], dopamine [23], pyrrole [15], melamine [24], ethylenediamine [25], benzenediamine [26], dicyandiamide [27], hexamethylenetetramine [28], benzimidazole [29], carbazole [30], cyanuric chloride [31], polyacrylonitrile [32], polyimide [33], polyindole [34] and chitosan [35] have been used as nitrogen source of NPCM with a content range of 0.23-31.70 wt.%. Generally, pyrolysis and activation of nitrogenous precursors at low temperature are favorable for nitrogen retention.…”

CO2 adsorption in porous carbon materials has attracted great interests for alleviating emission of post-combustion CO2. In this work, a novel nitrogen-doped porous carbon material was fabricated by carbonizing the precursor of melamine-resorcinol-formaldehyde resin/graphene oxide (MR/GO) composites with KOH as the activation agent. Detailed characterization results revealed that the fabricated MR(0.25)/GO-500 porous carbon (0.25 represented the amount of GO added in wt.% and 500 denoted activation temperature in °C) had well-defined pore size distribution, high specific surface area (1264 m2·g−1) and high nitrogen content (6.92 wt.%), which was mainly composed of the pyridinic-N and pyrrolic-N species. Batch adsorption experiments demonstrated that the fabricated MR(0.25)/GO-500 porous carbon delivered excellent CO2 adsorption ability of 5.21 mmol·g−1 at 298.15 K and 500 kPa, and such porous carbon also exhibited fast adsorption kinetics, high selectivity of CO2/N2 and good recyclability. With the inherent microstructure features of high surface area and abundant N adsorption sites species, the MR/GO-derived porous carbon materials offer a potentially promising adsorbent for practical CO2 capture.

“…In CO 2 mitigation technologies, CO 2 adsorption with kinds of solid adsorbents receives a great attention because of the large adsorption capacity and less corrosion to the equipment [6]. For efficient adsorption, various organic amine functionalized adsorbents are developed, such as molecular sieves [7][8][9][10], carbon [11][12][13][14], metalorganic framework (MOFs) materials [15][16][17][18], polymer [19][20][21] and bimetal materials [22].…”

In the present work, zirconium-doped metal oxide of TiO 2 (Zr N ) was synthesized and functionalized with different amount of tetraethylenepentamine (TEPA). The physical properties of the materials were tested using temperatureprogrammed desorption of NH 3 , X-ray diffractometer, X-ray photoelectron spectrometer, scanning electron microscope, transmission electron microscope, energy dispersion spectrum, Inductively coupled plasma atomic emission spectroscopy, Infrared spectrometer, N 2 adsorption-desorption analyzer, energy dispersion spectrum and thermogravimetric analyzer. Zr species has a positive effect on the enhancement of the thermal stability and amine utilization. After the introduction of Zr, the decomposition temperature of TEPA is improved to 180℃. Over TEPA decorated adsorbents, physical adsorption and chemical adsorption occurs simultaneously. When the adsorption time is 75℃, CO 2 flow rate is 20 mL/min, the adsorbent of TEPA(40)/TiO 2 (Zr 0.1 ) exhibit a remarkable amine utilization of 83.5%.

“…Two peaks at 164 eV and 165 eV are related to C-S functional group in thiophene-S [27] or C=S [28]. The peaks at 166 eV and 167 eV are ascribed to oxidized sulfur/sulfoxides [16,25] in TsOH-C and TsOH-STC. Oxidized sulfur functionalities constitute 18.2% of sulfur functionalities in TsOH-C and that of TsOH-STC is 22.3%.…”

Herein, porous carbon materials were prepared using p-toluenesulfonic acid (TsOH) as a carbon source with (TsOH-STC) and without (TsOH-C) presence of MgCl2.6H2O. The products were evaluated in terms of CO2 (carbon dioxide) adsorption performance, texture and surface chemical structure. Both samples contain oxidized sulfur on their surface according to X-ray photoelectron spectroscopy (XPS). TsOH-STC has a 3D porous network, but TsOH-C consists of a dense structure. It was understood that TsOH-C is not suitable to be analyzed with N2 adsorption at cryogenic temperatures probably due to restricted access to narrow pores due to lack of external surface. The CO2 uptakes are 0.78 mmol g-1 for TsOH-C and 0.67 mmol g-1 for TsOH-STC at flue gas conditions (0.15 bar and 298 K) of coal fired power plants, which is a projection of ultramicropore (pores smaller than 0.7 nm) volume in 0.5 nm range. TsOH-C has CO2 uptake capacity of 2.21 mmol g-1 and TsOH-STC reaches 2.47 mmol g-1 at 1 bar at 298 K. Maximum CO2 adsorption enthalpy (Qst) value for TsOH-C is 24.9 kJ mol-1 and that of TsOH-STC is 25.7 kJ mol-1. IAST (ideal adsorbed solution theory) selectivities (CO2:N2 = 15:85) of the samples are 13.5 for TsOH-STC and 19.7 for TsOH-C at 1 bar. It was shown in this study that salt templating with MgCl2 does not influence ultramicroporosity development and provide moderate level CO2 capture performance. However, templating induces formation of supermicropores (micropores larger than 0.7 nm), large mesopores and macropores on TsOH derived carbons.
