The experiment was conducted to synthesize carbon nanospheres of different sizes by controlling the temperature in polycondensation reaction of glucose under hydrothermal process. The surface morphology, structural, optical, and thermal properties of as synthesized particles were characterized using TEM, SEM, XRD, Raman spectroscopy, TGA, and DSC. The particles morphology and dispersity were modified and reduced their size after calcination at 500oC
in comparison to those without calcinated. Thermal study also indicates particles change their phase from amorphous to crystalline and achieve thermal stability after
520oC
, which can also be verified by presence of D-band and G-band in Raman spectrum. Overall results indicate that the carbon nanospheres are hard solids and highly dispersed with size ranges from 50 nm to 300 nm.
