Recent Article Published: High-Capacitance Hybrid Supercapacitor Based on Multi-Colored Fluorescent Carbon-Dots

tocfiguresonMulti-colored, water soluble fluorescent carbon nanodots (C-Dots) with quantum yield
changing from 4.6 to 18.3% were synthesized in multi-gram using dated cola beverage
through a simple thermal synthesis method and implemented as conductive and ion
donating supercapacitor component. Various properties of C-Dots, including size, crystal
structure, morphology and surface properties along with their Raman and electron
paramagnetic resonance spectra were analyzed and compared by means of their
fluorescence and electronic properties. α-Manganese Oxide-Polypyrrole (PPy) nanorods
decorated with C-Dots were further conducted as anode materials in a supercapacitor.
Reduced graphene oxide was used as cathode along with the dicationic bis-imidazolium
based ionic liquid in order to enhance the charge transfer and wetting capacity of …
