Tailoring Low-Cost Granular Activated Carbons Intended for CO2 Adsorption

Synergetic Effect of Microporosity, Composition, and Surface Functionality of Nanoporous Activated Carbon: An Interface for CO2 Capture and Supercapacitor Applications

“…Also, the current synthetic methodology offers a few advantages: (1) the synthesis of NAC involves the use of a novel precursor, namely waste floral foam, which subsequently contributes to the neutralization of this waste. (2) The different additives in the floral foam allow for the in situ doping of heteroatoms, such as O and N, in the NACs, and there is no need for additional chemical doping treatment. (3) The methodology proposed here also offers flexibility for tailoring the porosity of NACs according to the desired requirement.…”

“…The mounting amount of carbon dioxide (CO 2 ) in the ecosystem is the primary source of environmental disturbance, potentially contributing to global warming, climate change, and ocean acidification . Excessive CO 2 emissions in the atmosphere are mostly driven by deforestation, chemical processes, and the combustion of fossil fuels and biomass . Furthermore, the energy crisis resulting from natural resource depletion and decreasing fuel availability has become a serious concern that requires immediate corrective action .…”

“…1 Excessive CO 2 emissions in the atmosphere are mostly driven by deforestation, chemical processes, and the combustion of fossil fuels and biomass. 2 Furthermore, the energy crisis resulting from natural resource depletion and decreasing fuel availability has become a serious concern that requires immediate corrective action. 3 As a result, CO 2 uptake and energy storing devices like supercapacitors have been extensively researched as potential solutions to the aforementioned problems.…”

Advancements in adsorption based carbon dioxide capture technologies- A comprehensive review

“…They reported that at 30 °C, CH 4 purification was more than 95 % with a 60 % recovery rate. Several adsorbent materials have been studied to be applied to PSA technologies for CO 2 adsorption and upgrading biogas such as zeolites [ [32] , [33] , [34] ] [ [32] , [33] , [34] ] [ [32] , [33] , [34] ], activated carbon [ [35] , [36] , [37] , [38] , [39] ], metal-organic frameworks (MOFs) [ [40] , [41] , [42] , [43] ] and carbon molecular sieves (CMS) [ 44 ]. The final output of a pressure swing adsorption process usually depends on several aspects such as isothermal conditions [ 45 ], configuration of the PSA process [ 46 ], and type of the adsorbent [ 40 , 47 ].…”

Novel Supported Ionic Liquid Adsorbents for Hydrogen Sulfide Removal from Biogas

“…et al, 2019). While activated carbon (AC) serves as a common, cost-effective, and readily available adsorbent material, it encounters challenges regarding selectivity, breakthrough time, and limited capacity (Nurhidayah et al, 2022;Lucena et al, 2020;Plaza et al, 2010). On the other hand, IL possess issues like viscosity, high cost and dynamic separation (Bárbara Burlini .…”
