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).
