This research investigates the design, fabrication, and testing of single-cell module supercapacitors. The supercapacitor consists carbon nanocomposites, which contain activated (AC), multiwall nanotubes (MWCNT), graphene (GR). coin pouch cell type supercapacitors were manufactured with AC: MWCNT: GR composite electrodes in a ratio 70:20:10 weight percent. Meanwhile, electrochemical characteriz...
This study describes a world of new carbon “fullerene” allotropes that may be synthesized by molten carbonate electrolysis using greenhouse CO2 as the reactant. Beyond conventional diamond, graphite and buckyballs, vast array unique nanocarbon structures exist. Until recently, was thought to unreactive. Here, we show can transformed into distinct nano-bamboo, nano-pearl, nano-dragon, solid holl...
The development of highly active, cheap and robust oxygen reduction reaction (ORR) electrocatalysts to replace precious metal platinum is extremely urgent and challenging for renewable energy devices. Herein we report a novel, green and especially facile hydrogel strategy to construct N and B co-doped nanocarbon embedded with Co-based nanoparticles as an efficient non-precious ORR catalyst. The...
