Synthesis and characterization of unsupported copper sulfide for mercury trapping in aqueous system / Yap Pei Lay

Two phase pure copper sulfides, rhombohedral phase digenite (Cu9S5) and hexagonal phase covellite (CuS) have been successfully prepared via hydrothermal method using copper nitrate and sodium thiosulfate without any assisting agent. The structural, chemical, and thermal properties of the as-synthesi...
