摘要

摘要本文研究了在200 ~ 800℃的不同温度下，热处理石墨样品在空气中的拉曼光谱特征与氧化温度的关系。我们的研究结果表明，石墨在空气中的热氧化导致二维振动模式的增强，同时降低了D振动模式的强度。此外，我们报告化学还原开始于550°C。此外，我们的结果表明，热氧化导致样品内的无序减少。关键词:拉曼光谱氧化六方环序度esp2杂化碳披露声明作者未报告潜在利益冲突。

Effect of oxidation temperature on Raman spectra of graphite samples

AbstractThe recent work investigates the relationship between the characteristics of the Raman spectra and the oxidation temperature of thermal-treated graphite samples in air at various temperatures ranging from 200°Cto 800 °C. Our findings indicate that thermal oxidation of graphite in air leads to the enhancement of the 2D vibration pattern while reducing the intensity of the D vibration pattern. Moreover, we report that chemical reduction begins at 550 °C. Furthermore, our results demonstrate that thermal oxidation causes a decrease in the disorder within the samples.Keywords: Raman spectragraphite oxidehexagonal ringsorder degreeSP2-hybridized carbon Disclosure statementNo potential conflict of interest was reported by the authors.
