Abstract In this study, carbon nanoparticles (CNP) have been synthetized by the method of hydrothermal carbonization (HTC), which entails low cost, minimum equipment requirement, and less synthesis time. In order to improve the characteristics and the mass yield of CNP, a variation in the HTC process has been developed; which consists in introducing a blend of organic solvent with water into the reactor, instead of only water. The precursor is the glucose and three organic solvents were tested: hexane, toluene, and butyl acetate at different reaction times: 1, 2 and 4 h. The size distribution of the CNP doesn't depend on the synthesis conditions. But, the mass yields of the CNP has an incredibly increase with the variation of process, this phenomenon is observed with all organic solvents at only 1 h of reaction time. With butyl acetate the highest degree of dehydration was achieved according to the Ven Krevelen diagram and the FT-IR spectra. Besides, with this organic solvent, the highest Photoluminescence Quantum Yield was reached.

使用溶剂辅助水热碳化生产碳纳米颗粒

摘要 在本研究中，碳纳米颗粒（CNP）采用水热碳化（HTC）方法合成，成本低，设备要求低，合成时间短。为了改善 CNP 的特性和质量产量，开发了 HTC 工艺的变体；这包括将有机溶剂与水的混合物引入反应器，而不仅仅是水。前体是葡萄糖，测试了三种有机溶剂：己烷、甲苯和乙酸丁酯，反应时间不同：1、2 和 4 小时。CNP 的尺寸分布不依赖于合成条件。但是，CNP 的质量产率随着工艺的变化而惊人地增加，这种现象在所有有机溶剂中仅在 1 小时的反应时间内观察到。根据文克列维伦图和 FT-IR 光谱，使用乙酸丁酯达到最高脱水程度。此外，使用这种有机溶剂，达到了最高的光致发光量子产率。
