Facile Fabrication of CuS Nanostructures with Enhanced Catalytic and Photocatalytic Degradation Performance on Methylene Blue

Graphical The catalytic and photocatalytic performance of the Copper sulfide (CuS) products prepared by using different copper sources are respectively studied. The catalytic performance of the CuS sample prepared via CuCl 2 as copper source is the best, and when H 2 O 2 is added to form a photo-Fenton catalytic system, it has excellent degradation ability for MB in both dark and light irradiation environments. 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 the photo-Fenton catalytic performance of the CuS materials in the degradation of organic dye MB. Via changing the copper source, the catalytic and photocatalytic performances of the CuS products prepared by using different copper sources such as CuSO 4 , Cu(NO 3 ) 2 , CuCl 2 , Cu(C 2 H 3 O 2 ) 2 were studied. The results indicated that due to the difference of copper sources, the catalytic performance of the obtained CuS samples varied greatly. For example, the catalytic properties of the CuS specimens prepared via CuCl 2 and CuSO 4 were significantly better than those of the products prepared using Cu(C 2 H 3 O 2 ) 2 and Cu(NO 3 ) 2 . Meanwhile, the degradation performance of MB by the same CuS specimen is better in a light irradiation condition than in a dark environment. Specifically, the catalytic performance of the CuS sample prepared via CuCl 2 as copper source was the best, and when H 2 O 2 was added to form a photo-Fenton catalytic system, it has excellent degradation ability for MB in both dark and light irradiation environments.
