Abstract

The invention provides a preparation method of three-dimensional porous nitrogen-doped graphene. The three-dimensional porous nitrogen-doped graphene is obtained by simultaneously using amino acid small molecules are a carbon source and a nitrogen source and sequentially performing roasting, grinding, pickling, washing with deionized water, washing with absolute ethyl alcohol and drying through a transition metal catalyst, the nitrogen source and a pore-forming activating agent are not needed to be added during the preparation process, the in-site porous nitrogen-doped graphene can be formed by an one-step method, and the three-dimensional porous nitrogen-doped graphene in different morphologies can be obtained according to different types of the transition metal catalyst. The method is simple and convenient, is low in cost and can be widely applied to the fields of a fuel cell, a lithium ion battery, a supercapacitor and the like, and mass production is facilitated.

Description

technical field

[0001] The invention relates to the technical field of new carbon materials, in particular to a preparation method of three-dimensional porous nitrogen-doped graphene, three-dimensional porous nitrogen-doped graphene and applications thereof. Background technique

[0002] Graphene is a two-dimensional material composed of a single layer of carbon atoms, which was accidentally discovered in 2004 by Professor Geim from the United Kingdom through mechanical exfoliation. Because of its excellent electrical conductivity, ultra-high mechanical strength, and huge specific surface area, graphene has caused a research boom since its discovery and has been widely used in many fields. Graphene has important applications in the cathode and anode of fuel cells. A large number of studies have shown that graphene can be directly used as a cathode oxygen reduction catalyst and exhibit high activity; in addition, graphene can also be used as an excellent catalyst carrier, th...
