Copper sulfide (CuS) particles were synthesized via photochemical method from an aqueous solution containing copper sulfate (CUSO4) and sodium thiosulfate (Na2S2O3) of different compositions. The particles of various compositions were deposited in acidic medium (pH similar to 3) for the duration of 1-2 hour photo irradiation. The amount of particles formed depended on the time of irradiation, about 75% of the reagents was converted into fine CuxS particles. The synthesized particles were then characterized by powder XRD, showed the particle had crystalline nature and FTIR spectrum was analyzed.
