Monodisperse Carbon Nanospheres with Hierarchical Porous Structure as Electrode Material for Supercapacitor

Carbon nanospheres with distinguishable microstructure were prepared by carbonization and subsequent KOH activation of F108/resorcinol-formaldehyde composites. The dosage of triblock copolymer Pluronic F108 is crucial to the microstructure differences. With the adding of F108, the polydisperse carbon nanospheres (PCNS) with microporous structure, monodisperse carbon nanospheres (MCNS) with hier...

Facile synthesis of CuCo2S4 as a novel electrode material for ultrahigh supercapacitor performance.

CuCo2S4 nanoparticles demonstrating outstanding electrochemical performances were firstly synthesized through a simple solvothermal approach without using any templates. CuCo2S4 synthesized in glycerol (CuCo2S4-glycerol) fulfills an ultrahigh capacitance of 5030 F g(-1) at 20 A g(-1) in a polysulfide electrolyte.

HIGH PERFORMANCE SUPERCAPACITOR ELECTRODE MATERIAL BASED ON FLOWER LIKE MoS2/REDUCED GRAPHENE OXIDE NANOCOMPOSITE

A simple and cost effective hydrothermal method has been done for the synthesis of MoS2 and MoS2/rGO nanocomposites. The prepared MoS2/rGO composite was characterized by XRD, FESEM and TEM which revealed the formation and as well as the morphological scenario of MoS2/rGO nanocomposite. Pure MoS2 and MoS2/rGO nanocomposite show 3D hierarchical flowery architecture where rGO nanosheets were inter...

Simple Synthesis of Molybdenum Disulfide/Reduced Graphene Oxide Composite Hollow Microspheres as Supercapacitor Electrode Material

MoS₂/RGO composite hollow microspheres were hydrothermally synthesized by using SiO₂/GO microspheres as a template, which were obtained via the sonication-assisted interfacial self-assembly of tiny GO sheets on positively charged SiO₂ microspheres. The structure, morphology, phase, and chemical composition of MoS₂/RGO hollow microspheres were systematically investigated by a series of technique...
