    摘要
  • 摘要: 以DMF（氮，氮-二甲基甲酰胺）/乙醇为电解质溶液，研究了煤炭在铅电极表面的电化学加氢作用。利用有机溶剂萃取得到电解产物，并对其进行表征。通过元素分析分析发现，电解产物H/C原子比有了显著提高，体现出该电解体系较高的加氢效率。红外光谱显示，电解过程中C=O 键和芳环结构得到了有效还原。煤分子结构中的桥键，如 C-O-C，也发生了裂解反应。通过 1H-NMR分析，进一步印证了煤电解过程中的结构变化，并提出了可能的反应机理。
    Abstract: The electro-hydrogenation of coal on Pb electrode in a mixed dimethylformamide-ethanol (DMF-EtOH) electrolyte was investigated. The hydrogenation product was in-situ extracted from the organic solvent and characterized. The electrolysis products show a significant increase in H/C ratio, indicating increased hydrogenation efficiency. IR spectroscopy shows the reduction of C=O bond and aromatic ring, as well as the cleavage of bridge bonds, such as C-O-C, are the main reactions during the electrolysis. This is also confirmed by the increase of γ-H content measured by 1H-NMR.
