葡萄糖基炭微球的制备与结构表征

Hydrothermal Synthesis and Characterization of Glucose--derived Carbon Spheres

以葡萄糖为碳源制备炭微球，考察了原料浓度、反应时间和反应温度对所得炭微球形貌和产率的影响，并测定了其表面官能团的种类和数量。结果表明，葡萄糖浓度为0．5mol／L、反应温度为180℃、反应时间为7h的条件下制备了粒径300nm左右、分数性较好的炭微球。所得炭微球表面合有丰富的羟基、羰基、羧基等含氧官能团，采用联碱中和法定量测定了上述官能团的含量。

Carbon microspheres have been produced under hydrothermal with glucose as carbon sources. It is found that the obtained carbon microspheres have good dispersion with the sizes about 300nm when the concentration of glucose solution fixed 0.5mol/L at 180℃ for 7h. The surfaces of the obtained carbon spheres are rich in functional groups such as hydroxy, carboxyl and carbonyl, and their amount is investigated by neutralization titration.
