WebMar 24, 2024 · With an N-containing MOF (ZIF-8) as the precursor, carbonization at higher temperatures leads to a higher degree of graphitization. Subsequent NH 3 etching of this highly graphitic carbon enabled the introduction of a higher content of pyridine-N sites and higher porosity. By optimizing these three factors, the resultant carbon materials ... WebThe effects of La2O3 catalyst on the graphitization degree and microstructure of the carbon/carbon composites were investigated by X-ray diffraction, scanning electron microscopy, and Raman spectroscopy. The results showed that La2O3 promoted the formation of more perfect and larger crystallites, and improved the electrical/mechanical ...

WebMar 23, 2024 · The synthesis effect of conventional approaches and the new one proposed by the team were compared. Following the team's improvements, a high degree of graphitization effect could be accomplished at a reduced temperature. Methodology. Two procedures were used to treat discarded pomelo peels (Figure 1). The pomelo peels … WebTheoretically, carbonaceous materials with a high degree of graphitization and large surface area are beneficial for Li + storage, and those with a large surface area and enlarged interlayer spacing are beneficial for Na + storage. However, synchronously realizing them in carbonaceous materials at moderate temperatures is still a huge … WebThe degree of graphitization of edge coke was higher than that of center coke. The carburizing effect of liquid metal was the main cause of the degradation of edge coke and made it smaller or even disappear. Center coke was degraded due to the combination of two factors: slag inserted into micropores on the surface of center coke loosened the ... jww 環境設定ファイル 編集
