Nano-porous architecture of N-doped carbon nanorods grown on graphene to enable synergetic effects of supercapacitance

A novel nano-porous 3D architecture of N-doped carbon nanorods arrays grown on the surface of graphene has been prepared by carbonizing polyaniline/graphene oxide (PANI-GO) composite with PANI nanorod arrays on both sides of GO nanosheets. The obtained carbon materials are entirely composed of regularly grown carbon nanorods on graphene with height of about 100 nm and width about 30 nm, showing...
