Abstract

The invention belongs to the technical field of a carbon material and specifically relates to a preparation method for metal nanoparticle-loaded nitrogen-doped porous graphene. The method comprises the following steps: adding metal precursor, pore-foaming agent hydrogen peroxide and nitrogen source ammonia into a graphene oxide aqueous solution, heating the mixed solution to 100-220 DEG C and then performing hydrothermal reaction, thereby acquiring a metal nanoparticle-loaded nitrogen-doped porous graphene composite material. According to the method, a graphene porous structure is constructed while the nitrogen doping and the metal nanoparticle loading are realized; the whole process is simple; the demand on equipment is low; the reaction condition is mild; the production cost is low; the prepared metal nanoparticle / nitrogen-doped porous graphene has the characteristics of large specific area, excellent catalytic performance, uniform distribution of loaded metal nanoparticles, and the like; the metal nanoparticle-loaded nitrogen-doped porous graphene can be applied to the fields of electro-catalysis, supercapacitor, lithium ion battery, organocatalysis, and the like.

Description

technical field

[0001] The invention belongs to the technical field of carbon materials and organic catalysis, and in particular relates to a preparation method of nitrogen-doped porous graphene loaded with metal nanoparticles. Background technique

[0002] Graphene has become an ideal carrier for catalysts due to its unique graphitized planar structure, high specific surface area and good electrical conductivity and many other excellent properties. Qiu Jianding et al [CN201010523363.5] loaded Pt nanoparticles on functionalized graphene for the field of electrocatalysis. Doping graphene with N, on the one hand, can effectively control the surface charge distribution and surface defect degree of graphene carbon materials [ACS Nano2012, 6, 7084-7091], on the other hand, the doped N can also support graphene The nucleation and growth of metal catalyst nanoparticles (such as M=Pt, Pd, Co, etc.) and the interaction between M—C have an impact, thereby further changing the perform...
