(a) Diffraction pattern of as-prepared MoS₂ nanoflowers with peaks at 13.55, 33.06, 35.22, 42.5, 49.82, 58.01, and 69.77. (b) SEM image of MoS₂ nanoflowers (Inset Raman Spectrum of MoS₂ nanomaterial with the band at 296.86, 346.87 and 390 cm⁻¹). (c) Raman band at 1357 and 1596 cm⁻¹ of 3D graphene. (d) SEM images of 3D graphene. (e) EDX spectrum of MoS₂-3D graphene hybrid. The flower like MoS₂@3D-graphene hybrid architecture has also been observed in SEM and high resolution TEM images shown in (f) and (g), respectively, which reveals the petals of MoS₂ nano-flowers along with the 3D-graphene network effectively enhance the overall surface area that impacts on high storage capacity, (h) The hybrid interface is further confirmed by the HRTEM analysis where the lattice spacing are calculated to be 0.65 nm for MoS₂ and 0.34 nm for graphene, respectively.
