Cobalt sulfide is the name for chemical compounds with a formula CoxSy. Well-characterized species include minerals with the formula CoS2 and Co3S4 and the synthetic material Co9S8. In combination with molybdenum the sulfides of cobalt are used as catalysts for the industrial process called hydrodesulfurization which is implemented on a large scale in refineries.Cobalt sulfides precipitate when aqueous solutions of cobalt(II) ions are treated with hydrogen sulfide.
