“…Before the heat-treated GNFs were washed with water, the CO 2 desorption isotherms of chemical-treated GNFs did not retrace the adsorption curve, but exhibited a large hysteresis. This result occurred because the presence of potassium oxide particles on the GNFs surfaces enhances the adsorption capacity of CO 2 due to the acid-base interaction [5,32]. After water washing, the adsorption and desorption isotherms of GNFs shown in these plots basically follow the same path, suggesting that the adsorption process is reversible and the adsorbed molecules can be recovered during the desorption process as shown in Fig.…”

“…CO 2 adsorption is typically used as a final polishing step in the hybrid CO 2 capture system [3]. Ideal CO 2 adsorbents should have the following characteristics: a high specific surface area, welldeveloped micro-and mesopores, and many active sites on the surfaces, such as amine functional groups and basic metal oxide [4][5][6]. Up to now, different types of adsorbents have been used for CO 2 adsorption, such as zeolites, alumina, mesoporous silica, CaO, and porous carbons [7][8][9][10][11].…”

“…[16][17][18][19][20][21][22] In particular, activated carbon has been used in CO 2 adsorption for many years due to their highly developed porosity, extended specific surface area, hydrophobicity of their surface chemistry, thermal stability, and low cost. Recently, methods used for the design of novel nanoporous carbons also need to satisfy the requirements of global energy and environment problems.…”

Nanoporous carbons with a high specific surface area were prepared directly from thermoplastic acrylic resin as carbon precursor and MgO powder as template by carbonization over the temperature range, 500-1000 °C. The effect of the carbonization temperature on the pore structure and CO 2 adsorption capacity of the obtained porous carbon was examined. The textural properties and morphology of the porous carbon materials were analyzed by N 2 /−196 °C and CO 2 /0 °C adsorption/desorption isotherms, SEM and TEM. The CO 2 adsorption capacity of the prepared porous carbon was measured at 25 °C and 1 bar and 30 bar. The specific surface area increased from 237 to 1251 m 2 /g, and the total pore volumes increased from 0.242 to 0.763 cm 3 /g with increasing the carbonization temperature. The carbonization temperature acts mainly by generating large narrow micropores and mesopores with an average pore size dependent on the level of carbonization of the MgO-templated nanoporous carbons. The results showed that the MgO-templated nanoporous carbons at 900°C exhibited the best CO 2 adsorption value of 194 mg/g at 1 bar.

CO 2 capture represents the key technology for CO 2 reduction within the framework of CO 2 capture, utilization, and storage (CCUS). In fact, the implementation of CO 2 capture extends far beyond CCUS since it will link the CO 2 emission and recycling sectors, and when renewables are used to provide necessary energy input, CO 2 capture would enable a profitable zero-or even negative-emitting and integrated energy-chemical solution. To this end, highly efficient CO 2 capture technologies are needed, and adsorption using solid adsorbents has the potential to be one of the ideal options. Currently, the greatest challenge in this area is the development of adsorbents with high performance that balances a range of optimization-needed factors, those including costs, efficiency, and engineering feasibility. In this review, recent advances on the development of carbon-based and immobilized organic amines-based CO 2 adsorbents are summarized, the selection of these particular categories of materials is because they are among the most developed low-temperature (<100°C) CO 2 adsorbents up to date, which showed important potential for practical deployment at pilot-scale in the near future. Preparation protocols, adsorption behaviors as well as pros and cons of each type of the adsorbents are presented, it was concluded that encouraging results have been achieved already, however, the development of more effective adsorbents for CO 2 capture remains challenging and further innovations in the design and synthesis of adsorbents are needed.Keywords: CCUS, CO 2 capture, adsorption, energy, material science INTRODUCTION CO 2 CAPTURE AND AN INTEGRATED ENERGY-CHEMICAL SOLUTIONThe atmospheric CO 2 concentration now exceeds 400 ppm (CO2Now.org, 2014), and its continuous increase is believed to be the major factor leading to global warming and climatic change (Crowley, 2000;Held and Soden, 2000;Patz et al., 2005). Kaya et al. and Hoffert et al. have quantified net CO 2 emissions in terms of population, economic activity, and energy-related factors using Eq. 1 (Kaya, 1995;Hoffert et al., 1998).where C is the net CO 2 emission, P is population, GDP is the gross domestic product that is used here as an indicator of economyrelated factor, and E is energy production. Therefore, GDP/P is the Per capita GDP, and E/GDP can be regarded as the energy intensity during production that is closely related to the efficiency of energy utilization. The last term, C/E, represents the carbon intensity during energy production. As for the development of the human society and life quality, it is improper to limit population and production, which means there is no solution to CO 2 reduction from the first and second term in Eq. 1. On the other hand, increase in the energy production/utilization efficiency and control of the carbon footprint during energy processes are the major strategies for CO 2 sequestration (third and fourth term in Eq. 1). The complete decarbonization of energy is believed to be the ultimate solution for the long-term sustainability, ...
