https://doi.org/10.1016/j.ccst.2022.100039 “Similar to N, other electronegative atoms (O, S and F) might also possess the potential as the doping sources to modify the carbon adsorbent
https://doi.org/10.1016/j.ccst.2022.100039 “Apart from acids and alkalis, various salts (e.g., KCl, ZnCl2, FeCl3, CaCl2 and KMnO4) exhibit great potentials as an activator of biomass carbons to modify
https://doi.org/10.1016/j.ccst.2022.100039 “It has been reported that acid-treatment generates a higher micropore volume than the alkali activation due to the stronger solubility of the volatile organic
https://doi.org/10.1016/j.ccst.2022.100039 “Generally, the major reaction steps in H2O activation include chemisorption, oxidation, gasification and water‒gas shift reaction (Lussier et al., 1998). Different from the homogeneous micropores formed under
https://doi.org/10.1016/j.ccst.2022.100039 “Under a CO2 atmospheres, carbon matrix is partially gasified into CO, simultaneously generating high porosity and surface area (Prauchner et al., 2016). Via activation of a series
https://doi.org/10.1016/j.ccst.2022.100059 “The N-functional groups of biochar are closely related to its performance in CO2 capture, as discussed in Section 4.2.2. Biochar is usually capable of capturing CO2 by physical
https://doi.org/10.1016/j.ccst.2022.100059 “Alkali activation is normally performed by soaking and stirring biomass or biochar in an alkaline solution for several hours. Alkaline metals and alkaline-earthy metals may
