A novel β-MnO₂and carbon nanotube composite with potent electrochemical properties synthesized using a microwave-assisted method for use in supercapacitor electrodes

Abstract

In this work, we report the synthesis of a novel β-MnO2/CNTs nanocomposite with good electrical conductivity for high-performance supercapacitors via a microwave-assisted method. The structure and surface morphology of the...

Hydrothermal synthesis of an SnO2–rGO nanocomposite using tea extract as a reducing agent for daylight-driven photocatalyst and supercapacitors

“…[18][19][20] To date, various transition metal oxides, such as TiO 2 , NiO, ZnO, MnO 2 , CeO 2 and SnO 2 , have been successfully investigated in the field of energy storage and photocatalytic degradation applications. [21][22][23][24][25][26][27][28][29] Among these metal oxides, SnO 2 has ideal properties to replace commercial TiO 2 materials. SnO 2 is an n-type semiconducting metal oxide with a wide bandgap of 3.6 eV; it has unique electrical and optical properties, exhibiting high electron mobility (B100-200 cm 2 V À1 s À1 ) and high chemical stability.…”

CNTs-Supercapacitors: A Review of Electrode Nanocomposites Based on CNTs, Graphene, Metals, and Polymers

“…Ngo et al [72] fabricated polydopamine/CNT/graphene oxide nanocomposites as the flexible symmetric electrode for the supercapacitor and demonstrated the SC of 217.4 F/g. The supercapacitors based on the CNTs/MnO 2 nanocomposite electrode have been developed to fabricate high-performance supercapacitors [73][74][75][76][77][78]. The dispersion of MnO 2 and conductive additives in an electrode are key factors in increasing the efficiency of the electrode.…”
