Copper(II) sulfide is a chemical compound of copper and sulfur. It occurs in nature as the dark indigo blue mineral covellite. It is a moderate conductor of electricity. A black colloidal precipitate of CuS is formed when hydrogen sulfide, H2S, is bubbled through solutions of Cu(II) salts. It is one of number of binary compounds of copper and sulfur (see copper sulfide). It has attracted interest because of its potential uses in catalysis and photovoltaics
