Porous reticular gold nano-sheet array and preparation method thereof

The invention provides a porous reticular gold nano-sheet array and a preparation method thereof, belongs to the technical field of a gold nano material, and solves the problem that the existing gold nano material is difficult to realize the mass production. The porous reticular gold nano-sheet array is prepared through the following steps of: (1) preparing electrolyte containing gold ions; (2) electrically precipitating the electrolyte; (3) forming a porous reticular gold nano-sheet array on a working electrode. The prepared porous reticular gold nano-sheet array is of a reticular structure which is formed by connecting a plurality of porous nano-sheets. The porous reticular gold nano-sheet array is prepared by adopting a one-step electro-precipitation method, the gold nano material with a multilevel structure can be directly prepared on a substrate material, and the gold nano-sheet array can be directly used for producing a function device. The preparation process is simple and controllable, the energy cons
