| Abstract:In this thesis, fructose-based carbon microspheres were prepared by hydrothermal carbonation and high temperature carbonation using fructose as carbon source, lignosulfonate and P123 as the synergistic templates, the assembly process and regulation mechanism of fructose under hydrothermal conditions were also studied. The results showed that the addition of lignosulfonate was a decisive factor for the formation of ripple protuberances on the surface of microspheres. The hollow and porous Yolk-Shell fructose-based carbon microspheres after high temperature carbonization possessed superior specific surface area of 535.04 m2/g and a pore volume of 0.26 cm3/g. In addition, they also exhibited good electrochemical properties， the specific capacitance was 96 F/g, energy density was 3.16 Wh/kg and power density was 28.06 W/kg when the current density was 0.1 A/g. |
