Abstract

A method of synthesizing a graphene-based material comprises exposing graphene-encapsulated metal nanoparticles, each nanoparticle comprising a graphene shell surrounding a metal core, to a cracking and welding gas composition under conditions sufficient to crack graphene shells and to reconstruct cracked graphene shells to form the graphene-based material.
