Description

technical field [0001] The invention belongs to the technical field of materials, and more particularly, relates to a device and method for preparing two-dimensional palladium sulfide nanomaterials. Background technique [0002] Since the discovery of graphene in 2004, transition metal sulfides, as two-dimensional (2D) layered materials, are becoming an important part of next-generation electronics and optoelectronics due to their favorable physical and chemical properties. As a member of the transition metal chalcogenide family, palladium sulfide will be widely used in optoelectronics, catalysis and other fields due to its excellent physical and chemical properties. [0003] The current methods for preparing two-dimensional layered materials include mechanical and liquid phase exfoliation, physical vapor deposition (PVD) and chemical vapor deposition. However, the preparation strategy of palladium sulfide two-dimensional nanomaterials by CVD method is rarely reported. Bec...
