Title : The impact of quantum carbon dots on hybrid supercapacitors of nitrogen-doped graphene with magnetic metal oxides


Quantum carbon dots (Cdots) was insitu hybridized to develop ternary NG/CM/magnetite hybrids for supercapacitor materials. When the EMFs of (0,8.98 mT) was applied to the electrochemical measurements of the NG/Cdots/Fe3O4 hybrid electrodes, the highest specific capacitance of (1438 F/g, 2213 F/g) was obtained at a scan rate of 5 mV/s. At 4 wt% content of Cdots contrast to that of NG included in the binary hybrids of NG/Magnetite and it has shown higher capacitance performance. Ternary NG/Cdots/Fe3O4 hybrid electrode has shown the highest specific energy density of (99.7 Wh/kg, 143.0 Wh/kg) at the specific power density of 400 W/kg under the EMF of (0, 8.98 mT), respectively. These reports show that suitable ternary hybrid materials effectively enhance the specific capacitance, increase the specific energy density and maintain the durability of supercapacitors under the EMF.


Dr. Fite studied applied science and nanotechnology at the National Taiwan University of Science and Technology (NTUST), Taiwan in 2021 and graduated as MSc in Quantum Optics Physics in 2014 from Addis Ababa University, Ethiopia. He then joined Wallaga University as an instructor, Ethiopia in 2021. He received his PhD degree in 2021 at NTUST. He has published two research articles in SCI (E) journals.
