| Abstract: | Molybdenum disulphide is a two-dimensional lamellar material similar to graphene. Its excellent magnetic properties,electrical properties,catalytic performance and optical properties are widely concerned by researchers. In this paper,four kinds of molybdenum disulfide nanoparticles with different morphology are prepared by hydrothermal method. Scanning electron microscopy(SEM) is carried out for the sample of molybdenum disulphide,and the degradation test of methyl orange solution is carried out in the dark box with the 200 W tungsten filament lamp as the light source. The absorbency of prepared sample solution is tested by ultraviolet visible light spectrophotometer. It is concluded that the methyl orange solution degradation rate is the highest with the nanoflake molybdenum disulfide. |
