“…Recently, a rapid growth of reports using groups of chemisorbents for CO 2 capture from dilute gas streams such as ambient air, liquid and solid sorbents prepared from alkali and alkaline earth metal oxides and hydroxides, sorbents prepared from amines, and designed metal − organic frameworks (MOFs) have been reported. [11][12][13][14] It has been proposed that physiosorbent materials such as zeolites, activated carbons, or MOFs typically perform poorly at low CO 2 partial pressures, offering very small CO 2 capture and low CO 2 selectivity. 5 As air capture deals with an extremely low CO 2 concentration (420 ppm), roughly 350 times lower than that found in a typical coal-based flue gas, liquid solvent materials have proven to be much more effective for DAC processes so far.…”

“…Among the solid sorbent materials, modified graphene-based sorbent materials have shown nearly 10 times more efficient CO 2 adsorption compared to other active carbon, zeolites or MOFs. [11][12][13][14] This is attributed to CO 2 adsorption on both sides of each graphene sheet that provides potentially larger surface area for adsorption, and additionally with surface modification of graphene using nitrogen rich compounds can enhance the CO 2 capture further. More recently, membrane separation is proposed and considered the most energy-efficient technique for CO 2 separation among the various separation technologies.…”

Highlights DAC can help deal with difficult to avoid emissions. Large-scale deployment of DAC requires serious government, private, and corporate support and investment particularly to offset the capital cost as well as operational costs. Further optimizations to the costs can be found in choice of energy source as well as advances in CO2 capture technology such as high capacity and selectivity materials, faster reaction kinetics, and ease of reusability. Abstract Direct air capture (DAC) technologies are receiving increasing attention from the scientific community, commercial enterprises, policymakers and governments. While deep decarbonization of all sectors is required to meet the Paris Agreement target, DAC can help deal with difficult to avoid emissions (aviation, ocean-shipping, iron-steel, cement, mining, plastics, fertilizers, pulp and paper). While large-scale deployment of DAC discussions continues, a closer look to the capital and operational costs, different capture technologies, the choice of energy source, land and water requirements, and other environmental impacts of DAC are reviewed and examined. Cost per ton of CO2 captured discussions of leading industrial DAC developers with their carbon capture technologies are presented, and their detailed cost comparisons are evaluated based on the choice of energy operation together with process energy requirements. Validation of two active plants’ net negative emission contributions after reducing their own carbon footprint is presented. Future directions and recommendations to lower the current capital and operational costs of DAC are given. In view of large-scale deployment of DAC, and the considerations of high capital costs, private investments, government initiatives, net zero commitments of corporations, and support from the oil companies combined will help increase carbon capture capacity by building more DAC plants worldwide.

“…Current emissions of greenhouse gases that exclude those from land-use change today are approximately 57% higher than in 1990 and 43% in 2000. CO2 levels are now alarming and indicate the need to take immediate action to prevent serious repercussions from climate change [8]. While, during the Paris Climate Conference (COP21), 195 countries decided to prevent a global temperature upsurge of less than 2 °C, it is now fairly common knowledge that CO2 emissions are predicted to increase by over 40% in 2040 compared with those of 2010, all due to the increase in energy demand.…”

“…Therefore, the reduction of the CO 2 concentration by the capture based on the adsorption process has attracted much attention. Different adsorbents such as metal-organic frameworks [1][2][3], zeolites [4], activated carbons [5], and carbon nanotubes [6] have been studied for CO 2 capture. Especially, graphene and graphene-based materials with two-dimensional structures and large surface area are promising candidates due to their high mechanical stability, thermal, and electrical conductivity.…”

Insights into Interaction of CO\(_2\) with N and B-doped Graphenes

Graphene is a promising candidate for CO2 capture and storage. Doping graphene with other elements is an effective way to modify its CO2 storage ability. The literature has shown that the N and B doping could change the adsorption strength of CO2 on the graphene substrate. However, there is no research available to elucidate the adsorption sites and the physical properties underlying the interaction of CO2 with the N and B doped systems. Therefore, this paper is devoted to clarifying the current topic using the self-consistent van der Waals density functional theory calculations. The results showed that the N and B doping increases and decreases the adsorption energy of CO2, respectively. The reason is that there are more peaks of the electronic density of states of CO2 participating in the interaction with the N p orbital than with the B p orbital.
