General Roxbyite Information : Chemical Formula: Cu1.78S : Composition: Molecular Weight = 145.18 gm Copper 77.91 % Cu: Sulfur 22.09 % S: 100.00 % : Empirical Formula: −0.6 to +0.2 V at pH 7–8) and over the entire pH range (Woods et al., 1987), to sorb iodide from aqueous medium.

Copper sulfide thin films of diverse morphologies ranging from cubic to snowy or irregular crystallites depending on the deposition temperature were observed. Some copper sulfides are economically important ores.. Canadian Mineralogist, 23, 61-76.

Morphology and carrier density are two important parameters to determine their LSPR properties.

Copper sulfide thin films and nanoparticles have been prepared via aerosol assisted chemical vapour deposition and solvothermal hot injection routes, respectively. Sulfide minerals are inorganic compounds CV’ s were used to study the electrochemical behavior of copper in potassium sulfide solutions sweeping from hydrogen evolution -1.8 V to +0. Djurleite was the only phase deposited by AACVD (350, 400 and 450 °C).

The electrochemical behavior of copper in sodium sulfide solutions are very complex and involve different processes depending in the potential range considered.

: Electrical Conductivity in Copper Sulfides… 195 The XRD spectra, Figure 1, recorded for the Cu xS films on FTO substrate show that films obtained at lower temperatures 250-285 ooC consist mostly of CuS (Covellite JCPDS-03-065-0603) with a crystallite size calculated from the Scherrer equation of 311-323 Å. Both routes employed heterocyclic amine based benzoylthioureato-copper(II) complexes as single source precursors.

In chemistry, a "binary copper sulfide" is any binary chemical compound of the elements copper …

Structural rearrangement of the oxidized chalcocite Cu 2– x S crystal lattice to roxbyite by aging is proven to release the copper vacancies.
AU - Terabe, Kazuya. AU - Aono, Masakazu.

Thin films of copper sulfide were also deposited by the Aerosol Assisted Chemical Vapour Deposition (AACVD).

Heterogeneous copper sulfide based nanostructures have attracted intense attention based on their potential to combine the plasmonic properties of copper-deficient copper sulfides with properties of other semiconductors and metals. Internet Links for Copper Sulphides Hide The structure of roxbyite is based on a hexagonal-close-packed framework of sulfur atoms with the copper atoms occupying these layers, all having triangular coordination. Morphology and carrier density are two important parameters to determine their LSPR properties. The crystal structure of roxbyite bears a strong kinship to those of low chalcocite and djurleite. Popovici, I., et al. Copper sulfides describe a family of chemical compounds and minerals with the formula Cu x S y.Both minerals and synthetic materials comprise these compounds. Batch equilibration of cuprous sulfide particles suspended in aqueous solutions containing iodide species has revealed significant consumption of iodide. Copper sulfide films with various phases such as mixed metallic Cu-chalcocite, chalcocite, roxbyite, and mixed roxbyite-covellite phases were formed with increasing sulfurization time. We use roxbyite copper sulfide (Cu 1.8 S) nanorods (figs.

Here, we demonstrate that the foreign … Copper sulfide films with various phases such as mixed metallic Cu-chalcocite, chalcocite, roxbyite, and mixed roxbyite-covellite phases were formed with increasing sulfurization time. We examined the structural and electrical properties of copper sulfide films as a function of the sulfurization time of 70-nm-thick Cu films. Prominent copper sulfide minerals include Cu 2 S and CuS . Roxbyite, Cu. Copper sulfide films with various phases such as mixed metallic Cu-chalcocite, chalcocite, roxbyite, and mixed roxbyite-covellite phases were formed with increasing sulfurization time. S1 and S2) as a model system, because Cu + cations exchange with several other cations to produce related metal sulfides (18 –20, 30). Copper sulfides describe a family of chemical compounds and minerals with the formula Cu x S y.Both minerals and synthetic materials comprise these compounds. We examined the structural and electrical properties of copper sulfide films as a function of the sulfurization time of 70-nm-thick Cu films.

The sulfide minerals are a class of minerals containing sulfide (S 2−) or persulfide (S 2 2−) as the major anion.Some sulfide minerals are economically important as metal ores.The sulfide class also includes the selenides, the tellurides, the arsenides, the antimonides, the bismuthinides, the sulfarsenides and the sulfosalts.
