2.1.3 Preparation of Mn0.05Cd0.95S/NiSe2
The MCS nanoparticles were anchored on the surface of NiSe2 by a simple physical mixing method. The MCS (2 g) was added into 30 mL ethanol and dispersed by sonication for 30 min. Then add a certain amount of NiSe2 to the above solution and stirred for 30 min. The mixed solution was evaporated by constant stirring at 80 oC. The resulting samples were filtered and washed with water and alcohol. The ultimate Mn0.05Cd0.95S/NiSe2products were labeled as MCNS-x (where x is displayed by the nominal weight percentage (wt %) of NiSe2 in Mn0.05Cd0.95S).
