Metallic 1T-MoS₂ with defect induced additional active edges for high performance supercapacitor application

Abstract

Influence of thiourea on the formation of active-edges and the metallic phase of MoS2 and investigation of its energy storage properties.

Construction of 1T@2H MoS2 heterostructures in situ from natural molybdenite with enhanced electrochemical performance for lithium-ion batteries

“…27,28 A new peak appeared at a low angle of 2q ¼ 7.26 , corresponding to the (001) crystal plane, with Na + insertion to form Na x MoS 2 . 29,30 The characteristic peak intensity of 1T@2H MoS 2 is lower than that of molybdenite concentrate, indicating the synergistic effect of hydrazine and sodium hydroxide expanded successfully natural molybdenite. 20,31 The XRF test (Table S3 †) further veried that aer the expansion of molybdenite concentrate, the content of Mo and S elements increased signicantly, while other impurities decreased greatly.…”

2-Dimensional layered molybdenum disulfide nanosheets and CTAB-assisted molybdenum disulfide nanoflower for high performance supercapacitor application

“…The d-spacing is 0.64 nm and ascribed to the (002) plane. 40 Obviously, the defects were generated at the edge sites and instantly inuenced the reduction of the charge transfer resistance in the electroactive material, which may be helpful to improve the charge storage capacity. It was conrmed that the CTAB-assisted MoS 2 nanoower morphology was more signicant due to the CTAB surfactant effect, which established that the high active edges improves the surface area as a result.…”

High-rate transition metal-based cathode materials for battery-supercapacitor hybrid devices

“…It has been proved that vacancy defects can promote electrochemical charge transfer achieving good conductivity and rate performance, because another additional defect level would be generated in the bandgap. [114][115][116] A number of fascinating state-of-the-art works have been reported. For example, Cao et al reported ultra-small oxygen vacancy-rich Co 3 O 4 /graphene composites with ultra-high-rate performance.…”
