“…Many researchers have conducted extensive studies on realizing the resource utilization of biomass as a carrier of catalyst or an adsorbent for gas and heavy metals [35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54]. Zhang et al designed poly(acrylic acid)-grafted chitosan and rice straw-based biochar to adsorb heavy metals in wastewater, which suggested selective adsorption of Cr 3+ , Pb 2+ , and Cu 2+ [36].…”

Every late autumn, fluttering poplar leaves scatter throughout the campus and city streets. In this work, poplar leaves were used as the raw material, while H3PO4 and KOH were used as activators and urea was used as the nitrogen source to prepare biomass based-activated carbons (ACs) to capture CO2. The pore structures, functional groups and morphology, and desorption performance of the prepared ACs were characterized; the CO2 adsorption, regeneration, and kinetics were also evaluated. The results showed that H3PO4 and urea obviously promoted the development of pore structures and pyrrole nitrogen (N–5), while KOH and urea were more conductive to the formation of hydroxyl (–OH) and ether (C–O) functional groups. At optimal operating conditions, the CO2 adsorption capacity of H3PO4– and KOH–activated poplar leaves after urea treatment reached 4.07 and 3.85 mmol/g, respectively, at room temperature; both showed stable regenerative behaviour after ten adsorption–desorption cycles.

“…The capture of CO 2 [ 6 , 7 ] could allow its use as a revalorized by-product, such as fuels, chemicals, and building materials, adding an economic incentive for CO 2 capture and the green economy, while also reducing the environmental footprint [ 8 , 9 ]. Different adsorbents such as the diamine-based hybrid-slurry system [ 10 ], porous carbons [ 11 , 12 ], silica [ 13 , 14 , 15 ], MOFs [ 16 , 17 , 18 ], metal oxides [ 19 , 20 , 21 , 22 ], hydrotalcites [ 23 , 24 ], and periodic mesoporous organosilicas (PMOs) have been studied recently for CO 2 capture.…”

The CO2 adsorption of a phenylene-bridged ordered mesoporous organosilica (PMO–benzene) was analyzed. The maximum capture capacity was 638.2 mg·g−1 (0 °C and 34 atm). Approximately 0.43 g would be enough to reduce the amount of atmospheric CO2 in 1 m3 to pre-industrial levels. The CO2 adsorption data were analyzed using several isotherm models, including Langmuir, Freundlich, Sips, Toth, Dubinin–Radushkevich, and Temkin models. This study confirmed the capability of this material for use in reversible CO2 capture with a minimal loss of capacity (around 1%) after 10 capture cycles. Various techniques were employed to characterize this material. The findings from this study can help mitigate the greenhouse effect caused by CO2.
