Adsorption separation is recognized as one of the effective approaches for CO2 capture, with activated carbon serving as a widely used adsorbent. As high-quality coal resources for activated carbon production are gradually being depleted, the use of bamboo, anabundant resource in China, as a raw material for activated carbon has become a rational alternative. This paper reviews the mechanisms influencing the CO2 adsorption performance of activated carbon, such as pore structure and surface chemistry, and thoroughly explores the relationship between its composition, structure, and CO2 adsorption performance. It focuses on the important process aspects of pore regulation, surface modification strategies, and molding techniques for bamboo-based activated carbon, summarizing research progress in the preparation and modification methods of bamboo-based activated carbon for CO2 adsorption.

FLIBs, which are foldable and have high energy densities, are becoming increasingly important as power sources for wearable devices, flexible electronics, and mobile energy applications. Carbon materials, especially carbon nanofibers, are pivotal in improving the performance of FLIBs by increasing electrical conductivity, chemical stability, and surface area, as well as reducing costs. These materials also play a significant role in establishing conducting networks and improving structural integrity, which are essential for extending the cycle life and enhancing the safety of the batteries. This review considers the role of electrospinning in the fabrication of critical FLIB components, with a particular emphasis on the integration of carbon materials. It explores strategies to optimize FLIB performance by fine-tuning the electrospinning parameters, such as electric field strength, spinning rate, solution concentration, and carbonization process. Precise control over fiber properties is crucial for enhancing battery reliability and stability during folding and bending.

The pyrolysis method affects the microstructure of the material, and ultimately its sodium storage performance. Our previous work has shown that pyrolysis in a sealed graphite vessel improved the sodium storage performance of the carbon, however the changes in its microstructure and the way this influences the sodium storage are still unclear. A series of hard carbon materials derived from corncobs (CCG-T, where T is the pyrolysis temperature) were pyrolyzed in a sealed graphite vessel at different temperatures. As the pyrolysis temperature increased from 1000 to 1400 °C small carbon domains gradually transformed into long and curved domains. At the same time, a greater number of large open pores with uniform apertures, as well as more closed pores, were formed. With the further increase of pyrolysis temperature to 1600 °C, the long and curved domains became longer and straighter, and some closed pores gradually became open. CCG-1400, with abundant closed pores, had a superior SIB performance, with an initial reversible capacity of 320.73 mAh g−1 at a current density of 30 mA g−1, an initial Coulomb efficiency (ICE) of 84.34%, and a capacity retention of 96.70% after 100 cycles.

The resulting material has exceptional properties as an electrode for high-energy supercapacitors. Compared to the material prepared by the direct carbonization of PW, its electrical conductivity was increased from 0.36 to 26.3 S/cm.

Several different carbon materials were produced from them by oxidation in air (350 °C, 300 mL/min) followed by carbonization (1000 °C in Ar), and the effect of the cross-linked structure on their structure and sodium storage properties was investigated. The results showed that the two pitch fractions were obviously different after the air oxidation. The TS fraction with a low degree of condensation and abundant side chains had a stronger oxidation activity and thus introduced more cross-linked oxygen-containing functional groups C(O)―O which prevented carbon layer rearrangement during the carbonization. As a result, a disordered hard carbon with more defects was formed, which improved the electrochemical performance. Therefore, the carbon materials derived from TS (O-TS-1000) had an obvious disordered structure and a larger layer spacing, giving them better sodium storage performance than those derived from the TI-PS fraction (O-TI-PS-1000). The specific capacity of O-TS-1000 was about 250 mAh/g at 20 mA/g, which was 1.67 times higher than that of O-TI-PS-1000 (150 mAh/g).\u0000\t\t\t\t<figure><img><ol><li>Download: Download high-res image (107KB)</li><li>Download: Download full-size image</li></ol></figure></div></div>","PeriodicalId":19719,"journal":{"name":"New Carbon Materials","volume":"40 2","pages":"Pages 409-421"},"PeriodicalIF":5.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143887652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chrome-tanned-leathershavings (CTLS) are a readily available waste product that can be transformed into porous carbon. We prepared an activated carbon by microwave pyrolysis combined with KOH activator using the CTLS as starting materials. The carbon had a specific surface area of 556 m2g−1 and a honeycomb-like structure. Two kinds of N-doped activated carbons were then synthesized by thermal decomposition of the activated carbon, either combined with urea, or impregnated with ethanolamine. Both N-doped activated carbons have an increased number of nitrogen and amine surface groups. However, only the urea treatment was effective in improving the initial capacity of the cell (1363 mAh g−1), which is probably linked to the sorption of long-chain polysulfides. This investigation confirms that it is possible to use the thermal decomposition of urea to obtain carbon materials from CTLS for use as the sulfur-host cathode in Li-S batteries and improve their performance.

The results show the following decreases (RE) in the initial concentrations of these pollutants, REDF=99.5%, REMB=96% and RECB=90% after 90 min of exposure to UV-Vis radiation using 0.6 mg of photocatalyst. Experiments also showed that the degradation rate of diclofenac (k = 0.1028 min−1) is respectively 3.5 and 6 times faster than the values for CB (k = 0.0298 min−1) and MB (k = 0.0174 min−1), probably due to the easier bond cleavage in DF. UV-Vis irradiated solutions of these pollutants were then analyzed by mass spectrometry to identify the species formed during photocatalysis and suggest possible degradation paths for MB, DF, and CB. Data showed that the degradation of DF involves the formation of a photocyclization product through loss of HCl molecule, clearly consuming less energy than that needed for the opening of the central aromatic ring in MB, or the loss of the N-methyl amide functional group for CB.\u0000\t\t\t\t<figure><img><ol><li>Download: Download high-res image (97KB)</li><li>Download: Download full-size image</li></ol></figure></div></div>","PeriodicalId":19719,"journal":{"name":"New Carbon Materials","volume":"40 2","pages":"Pages 438-455"},"PeriodicalIF":5.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143887619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
