SEM analysis of the as-prepared MoS₂@CNFIG: SEM images of a overall structure (scale bar = 50 μm) and b, c cross section of MoS₂@CNFIG hybrid (scale bars, b 10 μm; c 5 μm); d MoS₂ layers homogeneously anchored on the CNF bridges (scale bar = 2 μm); e SEM image of an endpoint of CNF coated with MoS₂ nanoflakes (scale bar = 1 μm); f SEM image of selected area of MoS₂@CNFIG hybrid with MoS₂ nanoflakes anchored on the carbon layers (scale bar = 500 nm); g TEM analysis of the MoS₂@CNFIG sample (scale bar = 500 nm); h, i HRTEM images with distinctive layer spacing of MoS₂ and carbon matrix (scale bars, h 10 nm; i 2 nm)
