Abstract

The invention relates to a method for growing an upright three-dimensional netlike noble metal nano-plate on a boron-doped diamond substrate, which comprises the following steps: firstly, when electro-deposition is used in an electrochemical technique, using hydrogen bubbles generated on the surface of a boron-doped diamond film substrate material as a dynamic template so as to obtain an upright three-dimensional netlike nano metal plate; and secondly, in the process of performing a chemical method, using the upright three-dimensional netlike nano metal plate as a template, and through substitution reactions, using high valent noble metal to replace the upright three-dimensional netlike nano metal plate so as to obtain the upright three-dimensional netlike noble metal nano-plate on a boron-doped diamond film. The special structure obtained by the method not only can give full play to the advantages of the boron-doped diamond, but also can greatly improve the specific surface area of the noble metal and effectively promote the diffusion of active reaction molecules in a hole pipeline by a netlike nano structure. Simultaneously, the special combination ensures that a working electrode obtains high electrochemical properties in material types and structural shapes.
