Phase identification and morphology of all samples were determined using X-ray diffractometer (XRD). The quantitative phase analysis was analyzed by fitting the XRD pattern using the GSAS-II...

XRD analysis revealed the formation of hexagonal covellite (CuS) and chalcocite (Cu2S) phases of copper sulfide. Despite these phases XRD data also showed the dominating hexagonal digenite...

Dec 1, 2015 · The obtained silver nanoparticles were analyzed by transmission electron microscopy (TEM) and X-ray diffraction (XRD). The results show that the as-synthesized silver nanoparticles are highly crystalline in nature, spherical in shape.

3.1. X-ray Diffraction Analyses Figure (1) show the XRD spectrum of Cu 2 S thin films pure and doped 3% Al at (R.T and Ta=573 K) deposited by thermal evaporation technique with (400nm) thickness. All these XRD pattern show polycrystalline nature of films and formation of Cu 2 S phase which is indexed in the

In the present study, dendritic Cu2S nanostructures were successfully synthesized via a simple hydrothermal route using cysteine as a capping agent, sulfide source, and reducing agent for...

Nov 1, 2013 · The as-prepared Cu 2 S nanostructure was characterized extensively by techniques such as XRD, TEM, SEM, FT-IR, PL, EDS and UV–Vis. The XRD studies showed that pure cubic Cu 2 S nanostructure has been produced and quantum confinement effects have been observed from optical absorption studies.

Dec 9, 2015 · Nanoporous Cu 2 S is firstly formed during the chemical dealloying process and then the Cu 2 S transforms into CuS. The nanoporous CuS exhibits excellent photocatalytic activity for the...

X-ray diffraction patterns for Cu 2 S samples synthesized under various conditions, measured at (a) RT and (b) 493 K, and (c) additionally measured at RT for the samples after induction-melting densification.

Dec 6, 2023 · The XRD patterns of Cu 2 S phases are well indexed based on a monoclinic-type structure with the space group P2 1 /c. The LK-99 matches the indexed database, which contains the impurity phase of Cu 2 S.

Cu2S is considered as a promising electrode material for lithium‐ion and sodium‐ion batteries owing to its flat charge‐discharge plateau as well as the abundant reserves. However, serious...
