Layered molybdenum disulfide (MoS2), a transition metal dichalcogenide, shows distinct optical, electrical, and physical properties at few-layer thickness. MoS2 nanosheets (NSs) widely explored for energy environmental applications but have limitations with respect to their electrical conductivity charge transfer characteristics due low surface area. These can be overcome by combining NSs carbon-based materials like graphene, carbon nanotubes, biochar, which enhance the in synergistic way. In this study, biochar (BC), carbon-rich material prepared from vegetable biomass through low-temperature pyrolysis has been combined bulk various ratios using an aqueous phase exfoliation method form NSs–biochar nanocomposites. The spectroscopic, structural, morphological studies confirmed interaction between BC, is well reflected facile process formation of few layered on BC without any agglomeration. electrochemical prove that incorporating into enhances capacitive behavior reduces resistance compared pristine biochar. This study provides ample scope composite storage applications, especially towards development electrode effect

Designing efficient electrode materials is necessary for supercapacitors but remains highly challenging. Herein, cobalt sulfide with crystalline/amorphous heterophase (denoted as Co(Al)S) derived from an Al metal-organic framework was constructed by ion exchange/acid etching and subsequent sulfidation strategy. It found that rational adjusting the sulfur source concentration to a suitable level favorable form 3D nanosheet-interconnected network architecture large specific surface area, which promoted ion/electron transport charge separation. Benefiting features of unique structure accompanied aluminum, nitrogen carbon coordinated in amorphous phase, optimal Co(Al)S(10) exhibited high capacity (1791.8 C g-1 at 1 A g-1), outstanding rate capability excellent cycling stability. Furthermore, as-assembled Co(Al)S//AC device afforded energy density 72.3 Wh kg-1 power 750 W kg-1, verifying Co(Al)S promising material storage devices. The developed scheme expected promote application MOF-derived electrochemical conversion fields.
