However, its efficient and scalable synthesis remains a significant challenge. We present a microwave-assisted approach for its continuous, large-scale production which enables synthesis at a rate of 0.6 g/h, with a yield of up to 90%. The synthesized GDY nanosheets have an average diameter of 246 nm and a thickness of 4 nm. We used GDY as a stable coating for potassium (K) metal anodes (K@GDY), taking advantage of its unique molecular structure to provide favorable paths for K-ion transport. This modification significantly inhibited dendrite formation and improved the cycling stability of K metal batteries. Full-cells with perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA) cathodes showed the clear superiority of the K@GDY anodes over bare K anodes in terms of performance, stability, and cycle life. The K@GDY maintained a stable voltage plateau and gave an excellent capacity retention after 600 cycles with nearly 100% Coulombic efficiency. This work not only provides a scalable and efficient way for GDY synthesis but also opens new possibilities for its use in energy storage and other advanced technologies.\u0000\t\t\t\t<figure><img><ol><li>Download: Download high-res image (156KB)</li><li>Download: Download full-size image</li></ol></figure></div></div>","PeriodicalId":19719,"journal":{"name":"New Carbon Materials","volume":"40 3","pages":"Pages 642-650"},"PeriodicalIF":5.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144501880","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}

The maximum oxidation rates of CeO2-HfB2-SiC coatings with 1%, 3%, and 5% CeO2 were 24.1%, 20.3%, and 53.2% higher than that of the unmodified HfB2-SiC coating, respectively.

CeO2 is a “coagulant” and “stabilizer” in the composite glass layer.

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.

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.

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}
