One-Step Synthesis of Cellulosed-Based Nitrogen-Doped Carbon Aerogel and Its CO2 Adsorption Performance

“…The two-site Langmuir–Freundlich (DSLF) isotherm model is often used to improve the accuracy of the multicomponent system selectivity data predicted by IAST theory. It has been shown that DSLF is suitable for a wide pressure range (0–100 kPa); the DSLF model is described by eq q = q m , 1 b 1 p 1 / n 1 1 + b 1 p 1 / n 1 + q m , 2 b 2 p 1 / n 2 1 + b 2 p 1 / n 2 …”

Mesoporous carbons from self‐assembled polymers

“…Furthermore, there was approximately 40% domain spacing reduction among all samples from the as‐cast state to the carbonized state, suggesting a remarkable degree of framework shrinkage under the high temperature pyrolysis step. Notably, MCs derived from Pluronic/resol systems have now been extensively studied and employed in various applications, including but not limited to, energy storage, 87,88 water purification, 89,90 separation membranes, 91,92 photovoltaics, 93,94 capacitors, 95,96 catalyst supports, 97,98 and gas capture 29,99 . Furthermore, this system was extended to the tri‐constituent co‐assembly of Pluronic/resol/tetraethyl orthosilicate (TEOS) for preparing MCs with enhanced surface area 100 .…”

Mesoporous carbon-based materials and their applications as non-precious metal electrocatalysts in the oxygen reduction reaction

“…By simply adjusting the ratios of phenol to the copolymer, OMC with two-dimensional hexagonal (p6m space group), body-centred cubic (Im3m), three-dimensional bi-continuous (Ia3d), or lamellar OMC were formed. Hydrothermal synthesis has also been employed in the fabrication of OMC structures, where all the precursors are mixed and then transferred to a Teflon-lined autoclave and heated for several hours at relatively low temperatures [53][54][55][56][57]. This is then followed by carbonisation to give the OMC structures.…”
