▎ 摘　　要

NOVELTY - A nitrogen-doped three-dimensional graphene loaded nanosilver composite material comprises nitrogen with doped quantity of 2.3-8.8%, self-assembled graphene sheet under the effect of the temperature and pressure to form the porous three-dimensional net-shaped structure, and the composite material of silver particles having particles size of 80-120 nm uniformly dispersed in the three-dimensional surface of graphite alkene with load quantity of 12-51 %. USE - Nitrogen-doped three-dimensional graphene loaded nanosilver composite material. ADVANTAGE - The nitrogen-doped three-dimensional graphene loaded nanosilver composite material can be prepared with increased three-phase reaction interface so as to improve the mass transfer velocity of the oxygen, and high conductivity in simple and cost-effective manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing nitrogen-doped three-dimensional graphene loaded nanosilver composite material.
