A newly developed route for the synthesis of hollow carbon nanospheres without introducing template under hydrothermal conditions was reported. Hollow carbon nanospheres with the diameter of about 100 nm were synthesized using alginate as reagent only. Many instruments were applied to characterize the morphologies and structures of carbon hollow nanospheres, such as XRD, TEM, and Raman spectroscopy. The possible formation and growth mechanism of carbon hollow spheres were discussed on the basis of the investigation of reaction influence factors, such as temperature, time, and content. The findings would be useful for the synthesis of more materials with hollow structure and for the potential use in many aspects. The loading of SnO(2) on the surface of carbon hollow spheres was processed, and its PL property was also characterized.

本文报道了一种在水热条件下无需引入模板即可合成中空碳纳米球的新路线。仅使用海藻酸钠作为试剂即可合成直径约为 100nm 的中空碳纳米球。采用多种仪器对碳空心纳米球的形貌和结构进行了表征，如 XRD、TEM 和拉曼光谱。基于对反应影响因素（如温度、时间和含量）的研究，讨论了碳空心球的可能形成和生长机制。这些发现将有助于合成更多具有中空结构的材料，并有可能在许多方面得到应用。在碳空心球表面负载了 SnO(2)，并对其光致发光性质进行了表征。
