Electrochemical hybrid supercapacitor was prepared with high performance activated carbon as anode material and self-made nano manganese oxide xerogel as cathode material.

Fractal characteristic of the porous structure of the additive silica xerogels;

Small angle X-ray scattering(SAXS) with synchrotron radiation as X-ray source is used to study the pore structure of Fe_2O_3 xerogels prepared by sol-gel procedure and then heat-treated at different temperatures.
