“…Moreover, carbon dioxide is a much safer chemical than KOH, which is typically used in chemical activation. On the other hand, materials obtained from beech wood compared to our previous studies [11,57] showed that it might be a competitive precursor in terms of the obtained sorption properties. An additional advantage is the high availability and relatively low price.…”

“…It is a result of the removal of smaller crystallites by the reaction with carbon dioxide. When smaller crystallites are removed, the average value shifts toward higher values [11]. Moreover, the interplanar distance is decreasing, which might suggest that heteroatoms, mostly oxygen, are being removed from the crystallites.…”

“…In case of activated carbon, crystallographic structures are just crystallites of graphite, although these crystallites tend to all have dimensions below 10 nm. Figure 3 contains the position of particular crystallographic planes, which can be distinguished in pure graphite material [11]. Moreover, during the activation, the carbon matrix is being removed through oxidizing (C + CO 2 = 2CO).…”

“…Moreover, during the activation, the carbon matrix is being removed through oxidizing (C + CO 2 = 2CO). Thus, the inorganic impurities present in the raw material increase their content with increasing burn off (please refer to the following literature for diffractograms of activated carbons obtained from polymers without any impurities [11]). This study used beech wood that contained calcium, which after the activation procedure was present in the form of calcium carbonate (pattern 01-086-2340).…”

“…While the adsorption of CO 2 and C 2 H 4 at 303 K, 1 atm requires micropores up to 0.7 nm and 1.0 nm, respectively [11], butane adsorption requires wider pores [12,13]. Therefore, it can be used as a model gas in order to test the adsorption capacity for some similar molecules.…”

The aim of this study was to prepare activated carbon materials with different porous structures. For this purpose, the biomass precursor, beech wood, was carbonized in an inert atmosphere, and the obtained charcoal was physically activated using carbon dioxide at 1273 K. Different porous structures were obtained by controlling the time of the activation process. Prepared materials were characterized in terms of textural (N2 sorption at 77 K), structural (XRD), and sorption properties (CO2, C2H4, C4H10). The shortest activation time resulted in a mostly microporous structure, which provided a high sorption of CO2. Increasing the activation time led to an increasing of the pores’ diameters. Therefore, the highest ethene uptake was obtained for the material with an intermediate activation time, while the highest butane uptake was obtained for the material with the highest activation time.

Herein, novel carbons that, owing to a high density of micropores (up to 79%) and N‐content (up to 14.9%), offering exciting potential for post‐combustion CO2 capture are reported. Given that little is known about how starting materials impact the structure and performance of carbons, three different microporous materials are pyrolyzed. These include a Co‐(metal‐organic framework) (MOF), a Co‐MOF‐polymer composite, and a coordination polymer derived from the same monomer and cobalt ions. Notably, the cobalt, which is required to drive the polymerization, is subsequently leached from the carbons via acid for its reuse in MOF synthesis. Next, various metrics including CO2 capacity, selectivity, isosteric heat of adsorption, breakthrough time and cyclability are assessed. The acid treated carbons adsorb 0.21, 0.99, and 1.11 mmol CO2 g−1, respectively, (313 K, 0.15 bar) with CO2/N2 selectivity ranging from 37 to 52. Due to superior capacity, the polymer‐derived carbons also reveal impressive breakthrough times in simulated flue gas mixtures (15% CO2/85% N2, 80% RH, 313 K) ranging from 33 to 40 min g−1. Similar performance is also observed under dry conditions and after pre‐saturation with water for 1.5 h. Remarkably, no loss in working capacity is observed after 100 CO2 TSA cycles (313 K/393 K).

Biomass is considered as a promising source to fabricate functional carbon materials for its sustainability, low cost, and high carbon content. Biomass-derived-carbon materials (BCMs) have been a thriving research field. Novel structures, diverse synthesis methods, and versatile applications of BCMs have been reported. However, there has been no recent review of the numerous studies of different aspects of BCMs-related research. Therefore, this paper presents a comprehensive review that summarizes the progress of BCMs related research. Herein, typical types of biomass used to prepare BCMs are introduced. Variable structures of BCMs are summarized as the performance and properties of BCMs are closely related to their structures. Representative synthesis strategies, including both their merits and drawbacks are reviewed comprehensively. Moreover, the influence of synthetic conditions on the structure of as-prepared carbon products is discussed, providing important information for the rational design of the fabrication process of BCMs. Recent progress in versatile applications of BCMs based on their morphologies and physicochemical properties is reported. Finally, the remaining challenges of BCMs, are highlighted. Overall, this review provides a valuable overview of current knowledge and recent progress of BCMs, and it outlines directions for future research development of BCMs.
