“…56 Additionally, weak diffraction peaks appeared at 2θ values of 27.6°and 59.4°, which can be attributed to the (111) and (116) crystallographic planes of the hexagonal phase of CuS. 34,57 The absence of any additional phase peaks or diffraction peaks associated with impurities confirms the purity of CuS. On the other hand, the XRD pattern of the CuS@PANI NCs exhibits several small diffraction peaks at 2 θ = 9.2°, 15.2°, 17.9°, 20.3°, and 23.9°, as well as large peaks at 2 θ = 27.7°, 28.8°, 33.1°, and 47.8°.…”
