Abstract

Monodisperse carbon spheres between 500 and 900 nm are hydrothermally synthesized from glucose on polystyrene seeds. Control over temperature, time, glucose concentration, and seed size yields hybrid spheres without aggregation and no additional spheres population. Pyrolysis transforms the hybrid into hollow carbon spheres preserving monodispersity. This approach provides a basis for functional carbon spheres applicable in photonics and energy storage.

摘要

500 至 900nm 之间的单分散碳球是通过在聚苯乙烯种子上的水热合成葡萄糖得到的。通过控制温度、时间、葡萄糖浓度和种子尺寸，可以得到没有聚集且没有额外的球体群体的杂化球体。热解将杂化球转化为空心碳球，同时保持单分散性。这种方法为适用于光子学和储能的功能碳球提供了基础。
