วัตถุประสงค์
:
1. To fabricate ACNFs/MnFe2O4, ACNFs/CuxMnyFe2O4: x+y=1, and ACNFs/AlxCuyMnzFe2O4: x+y+z=1 composite nanostructures in a variety conditions by electrospinning followed by carbonization and activation process, respectively.
2. To characterize the effect of carbonization temperature (500, 600 and 700 oC) on the structure, the crystallite size and the electrochemical properties of ACNFs/MnFe2O4 composite nanostructures. How the remaining carbons affected on the electrochemical properties is mainly focused.
3. To characterize the effect of activation process on the electrochemical properties of the prepared samples. How the surface area affected on the electrochemical properties is focused.
4. To characterize the effect of the Cu doping on the electrochemical properties of ACNFs/MnFe2O4, composite nanostructures. The effect of the contents of Cu on the electrochemical performance has been investigated.
5. To characterize the effect of the Al doping on the electrochemical properties of ACNFs/CuMnFe2O4, composite nanostructures. The effect of the contents of Al on the electrochemical performance has been investigated.
6. To study the phase transition in the charge/discharge process by in-situ X-ray absorption spectroscopy.
