“…For instance, nitrogen doped C‐KOH‐4 prepared from wasted CDs and DVDs by Jaroniec et al. showed a high S BET of 2240 m 2 g −1 , but the CO 2 uptake at 273 K was 5.8 mmol g −1 , the lower uptake could be attributed to the generation of abundant mesopores under harsh activation conditions; carbon material KBM‐700 with MOF as the carbon and nitrogen source had a high nitrogen content of 10.16 wt %, the low CO 2 uptake of 4.75 mmol g −1 was due to the fact that the microporosity in KBM‐700 was greatly contributed by micropores larger than 1 nm . The adsorption isotherms of Agar‐0.5‐550‐1 and Agar‐0.5‐600‐1 are very close, but an obvious deterioration of CO 2 uptake is witnessed when the activation temperature reaches 650 or 700 °C.…”

“…Nitrogen doped carbons are usually synthesized by either using nitrogen containing precursors including polymers, metal‐organic frameworks (MOFs) and biomass, or the post modification of carbons with nitrogen containing chemicals such as NH 3 . Compared with the latter, the pyrolysis of nitrogen containing organics is very attractive because a homogeneous incorporation of nitrogen into the carbon material can be realized .…”

An efficient carbonaceous CO2 adsorbent with doped nitrogen element is derived from agar. Agar was mixed with urea and the mixture was then carbonized. After chemical activation with KOH, nitrogen doped microporous carbon was obtained. The nitrogen content was up to 8.58 wt %, depending on the preparation conditions. The CO2 adsorption properties, including the adsorption isotherms, the isosteric heat of adsorption and the adsorption selectivity were studied. The highest CO2 uptake of 6.5 mmol g−1 (273 K, 1 bar) was achieved by a carbon activated at 600 °C with moderate nitrogen content, while the carbon activated at 550 °C exhibited the best CO2/N2 selectivity of 37. The current work exploits the potential use of agar as carbon precursor for CO2 adsorbent, and provides a convenient and effective approach to nitrogen doping.

Carbon‐based adsorbents for post‐combustion capture: a review

et al. 2018

View full text Add to dashboard Cite

Carbon dioxide capture is regarded as an effective method of greenhouse gas reduction. Post‐combustion capture from power plants will play a key role in CO2 abatement due to their important contribution to total CO2 emissions. Compared with the state‐of‐the‐art amine scrubbing technology, adsorption‐based post‐combustion capture (PCC) possesses excellent potential for lowering energy demand, and thus the total cost. Due to their relatively weak interaction with CO2, carbons showed lower adsorption capacity during PCC as compared with some benchmark materials (e.g. amine‐based adsorbents); however, their high cyclic stability and fast adsorption/desorption kinetics suggest that carbons have the important potential to achieve an optimized or balanced performance, and thus provide a low‐cost PCC process. In this review, we present preparation options and consider the structure‐performance relationship in CO2 capture with carbons, and summarize recent progress on using carbons for CO2 capture with special focus on PCC. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd.

production, especially for hydroelectricity, sunlight, and wind energy, which cannot be gathered or released when they are needed. [5][6][7][8] Electrochemical energy storage devices provide a promising approach for the storage of electric energy from these sources. [9][10][11] Currently, carbonaceous materials have attracted much interest for their extensive applications including adsorption, [12] catalysis, [13] batteries, [14] fuel cells, [15,16] supercapacitors, [17,18] and drug delivery and imaging. [19] In addition, some sensors are also one of the important applications of carbonaceous materials, because they are closely related to human health. [20,21] For instance, Emran and co-workers [22] constructed ultrasensitive biosensors with N-doped mesoporous carbon (NMC)-based electrodes for in vitro monitoring of DA released from living cells. With the further study of the experiment, they also designed a series of S-doped carbon materials for a wider detection of DA, UA (uric acid), and AA (ascorbic acid). [23,24] The advantages of easy preparing, nontoxic and excellent electrical conductivity of carbonaceous materials, which are rare among energy storage materials, make carbonaceous materials superior to most of the energy storage materials. [25][26][27] There are varieties of approaches for the preparation of carbon materials, such as directly carbonizing from organic precursors, physically or chemically carbonizing from carbon, template methods using zeolites and mesoporous silica, solvothermal and hydrothermal methods with elevated temperature, the electrical arc methods, and chemical vapor decomposition (CVD) methods. [28][29][30][31][32][33][34] Among all these approaches, directly carbonizing from organic precursors is the most frequently used method to prepare nanoporous carbons (NPCs) due to its flexibility and simplicity. [35][36][37] However, these NPC materials present certain drawbacks, such as low surface areas, disordered structures, and ununiformed sizes, which will greatly limit their applications. [25] As studies have progressed, researchers found that carbon materials derived from metalorganic frameworks (MOFs) could overcome these limitations.Metal-organic frameworks, which are also named porous coordination polymers (PCPs), are crystalline porous materials with periodic network structures formed by metal ions (or metal clusters) and organic ligands. [38][39][40][41][42] They are usually prepared by solvothermal methods and used as precursors or templates to form nanostructured materials. [43][44][45] So far, many researchers have highlighted the advantages of MOFs. For Carbon materials derived from metal-organic frameworks (MOFs) have attracted much attention in the field of scientific research in recent years because of their advantages of excellent electron conductivity, high porosity, and diverse applications. Tremendous efforts are devoted to improving their chemical and physical properties, including optimizing the morphology and structure of the carbon materials, compositing them wi...
