Facile access to template-shape-replicated nitrogen-rich mesoporous carbon nanospheres for highly efficient CO₂ capture and contaminant removal

Abstract

Novel nitrogen-rich mesoporous carbon nanospheres (NMCN) with high surface area and ordered pore geometry are prepared via a facile pathway for efficient CO2 capture and contaminant removal applications.

Straightforward synthesis of multifunctional porous polymer nanomaterials for CO2 capture and removal of contaminants

“…MSN-Br was synthesized via the reaction of MSN-NH 2 with BIBB, following our previously reported procedure. 54,57…”

“…Initiator grafting density ( G I ) was estimated using TGA and eqn (1): 54,55,57 where W % initiator + silica , W % silica , N A , M initiator and S sp represent the weight loss of MSN-Br between 120 °C and 600 °C (= 22.8%), weight loss of the neat MSN between 120 °C and 600 °C (= 6.7%), Avogadro's number, molar mass of the initiator moiety (= 150 g mol −1 ) and specific surface area of MSN-Br (1290 m 2 g −1 ).…”

“…MSPGMAN-CH 2 Cl was synthesized via SC-ATRP 55 of (GMA + VBC) as the monomers (using various mol% of VBC with respect to GMA) using a CuCl/CuCl 2 /PMDETA catalytic system in the presence of MSN-Br as the initiator at 60 °C, following an earlier reported procedure. 54…”

Preparation of a reusable and pore size controllable porous polymer monolith and its catalysis of biodiesel synthesis

“…During the past decades, porous materials including organic, inorganic and organic-inorganic materials have been extensively studied [1][2][3][4][5][6][7][8][9][10] due to their special physicochemical properties. Porous materials have been used in various elds, such as energy storage, [11][12][13][14] energy conversion, [15][16][17][18] adsorption, [19][20][21][22][23][24][25] catalysis, [26][27][28] sensing, [29][30][31] CO 2 capture, [32][33][34][35][36] etc. In recent years, the investigation of porous organic polymer (a class of highly crosslinked amorphous polymers possessing nano-pores) based catalysts has attracted signicant attention owing to their conned pore space and high surface area which is benecial for improving catalytic performance and stability.…”

Carbon Dioxide Captured on a Wet Si−C Composite Material with a Surfactant‐derived Carbon Film

“…Research and development of high‐efficiency CO 2 capture technology are urgent. Many solvents and solid sorbents interact strongly with CO 2 , such as amine‐functionalized porous materials, [2] porous polymers, [3] nitrogen‐rich mesoporous carbon nanospheres, [4] amine‐impregnated mesoporous silica nanotube, [5] and metal‐organic frameworks, [6] were used in DAC (direct air capture) technologies [7] . At present, the chemical absorption method of amine solution restricts its further development due to its large energy consumption, strong corrosiveness, and easy loss of absorbent [8] .…”
