Combustion synthesis of N-doped three-dimensional graphene networks using graphene oxide-nitrocellulose composites

We demonstrate a novel method to prepare high-quality and uniform nitrogen-doped, three-dimensional, graphene networks through combustion of graphene oxide (GO)-nitrocellulose composites. The N-doped 3D graphene networks have tunable porous morphology and the pore size can be controlled by adjusting the concentration of GO in the nitrocellulose matrix. This new method is a simple method to obtain nitrogen-doped graphene networks and has potential applications in energy storage and conversion, catalysis, and sensors.
