Phase Engineering, Structural Characterization of 1T-MS 2 （M
发布时间：2021-03-07 03:12
The two-dimensional layered material is the novel type of materials.The unique layered structure features give it excellent physical and chemical properties and broad application spectrum.Among these,two-dimensional transition metal chalcogenides（TMDs）are particularly prominent.In this thesis,we focused on the design of the metallic phase 1T-MS2（M =Mo/W）,and their related photocatalytic and supercapacitor properties in detail.The results are expected to be suitable for the future rati...
