Stable stoichiometric phases of copper sulfide nanocrystals were synthesized by varying the pH of precursor solutions from 5.5–9.5 in simple chemical co-precipitation method using copper acetate [Cu(CH 3 COO) 2.H 2 O] and Sodium thiosulfate Na 2 S 2 O 3.5H 2 O as precursors.

Copper sulfide layers were formed on polyamide PA 6 surface usingthe sorption-diffusion method. From: Extractive Metallurgy of Copper (Fifth Edition), 2011 or semiconductive copper sulfide layers varies in the interval 1 < x < 2. Metallhuettenwes., 13, 313–322 (1960) in German. It has the chemical formula CuFeS 2. The sulfur is changing from a solid to a liquid, and the copper turns into a black substance which is at the second oxidation state. Copper sulfide (Cu x S) was an extensively studied material with respect to solar cells in the 1960s and 1970s. The copper sulfide crystal structure plays a key role in the mechanism by which cation exchange occurs and the product that forms. Stds.

[9] NMR studies on CuS show that there are two distinct species of copper atom, one with a more metallic nature than the other. The effects of different parameters, such as synthesis parameters, particle size, bandgap energy, surface area, and morphology on the photocatalytic activity of copper sulfide heterojunctions for dyes degradation is also highlighted. Fac. The naturally occurring mineral binary compounds of copper and sulfur are listed below. 7 Answers. Geol., 72(8), 1524–1542 (1977). Both minerals and synthetic materials comprise these compounds.

Frenzel, “The Cu Excess of ‘Blue-Remaining’ Covellite”,Neues Jahrb. J. Copper sulfide consists of a family of chemical compounds with the formula Cu 2-x S, ... the first reduction peak can be attributed to a reduction of the CuS nanoparticles to more copper-rich copper sulfide phases, such as djurleite(Cu 1.94 S) or chalcocite (Cu 2 S). Acid-volatile sulfides (AVS) are an important metal-binding phase in sediments. Phys., 71(3), 407–414 (1974) in French. Miner. Through deliberately designed colloidal synthesis, we are able to selectively grow nanoshells comprising copper sulfides of specifically targeted crystalline phases and Cu/S stoichiometries, such as covellite (CuS), digenite (Cu1.8S), and nonstoichiometric Cu2–xS, on the surfaces of Au nanoparticle cores.
