Chemistry & industry
Applications
UsesCopper(II) sulfide is used in antifouling paints, mixed catalysts and to develop aniline black dyes in textile printing. Further, it is used as a varnish pigment and an oxidizing agent. In addition, it is used as a component of solid state electrodes and thin-film solar cell with cadmium sulfide. It is a moderate conductor of electricity and used in photovoltaics.
UsesIn antifouling paints; in preparation of mixed catalysts; in development of aniline black dye in textile printing.
General DescriptionCu63 NMR, X ray photoelectron spectroscopy,2 copper sulfide CuS was studied in detail.
Preparation methods
PreparationCopper(II) sulfide is prepared by heating copper(I) sulfide in the presence of excess sulfur in a hydrogen atmosphere. Ethanol solutions of anhydrous copper(II) chloride precipitate the copper(II) sulfide on the addition of hydrogen sulfide.
