Graphene/Ruthenium Active Species Aerogel as Electrode for Supercapacitor Applications

Ruthenium active species containing Ruthenium Sulphide (RuS₂) is synthesized together with a self-assembled reduced graphene oxide (RGO) aerogel by a one-pot hydrothermal synthesis. Ruthenium Chloride and L-Cysteine are used as reactants. The hydrothermal synthesis of the innovative hybrid material occurs at 180 °C for 12 h, by using water as solvent. The structure and morphology of the hybrid ...

Metallic 1T phase MoS2 nanosheets as supercapacitor electrode materials.

Efficient intercalation of ions in layered materials forms the basis of electrochemical energy storage devices such as batteries and capacitors. Recent research has focused on the exfoliation of layered materials and then restacking the two-dimensional exfoliated nanosheets to form electrodes with enhanced electrochemical response. Here, we show that chemically exfoliated nanosheets of MoS2 con...

A highly ordered titania nanotube array as a supercapacitor electrode.

We report the synthesis of self-organized titania nanotubes and nanocrystalline titania powders employing an alternative and novel approach. Integrating these nanostructures in a binder-free working electrode improved the capacitance up to 911 μF cm(-2), which is around one to two orders of magnitude higher than the conventional electric double layer capacitors.

Pseudo-capacitive performance of titanate nanotubes as a supercapacitor electrode.

Layered titanate H2Ti3O7 nanotubes were synthesized and firstly used as a supercapacitor electrode in a non-aqueous electrolyte. They exhibited the specific capacitances as high as 414 and 306 F g(-1) at 0.5 and 10 A g(-1), respectively, and 82% of the specific capacitance at the 10th cycle can be retained after 1000 cycles.
