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 SnO2on the
surface of carbon hollow spheres was processed, and its PL
property was also characterized. Keywords:Synthesis;
