Abstract Copper sulfide (CuS) is a p‐type semiconductor material with narrow band gap and easy to be excited by visible light, which makes it has broad application prospect in the field of organic pollutant treatment. This work provides some significant insights into photo‐Fenton catalytic performance CuS materials degradation dye MB. Via changing copper source, photocatalytic performances products prepared using different sources such as CuSO 4 , Cu(NO 3 ) 2 CuCl Cu(C H O were studied. The results indicated that due difference sources, obtained samples varied greatly. For example, properties specimens via significantly better than those . Meanwhile, MB same specimen light irradiation condition dark environment. Specifically, sample source was best, when added form system, excellent ability for both environments.
