Using Carbonate as the carbon source,multi-layer graphene sheets were synthesized instantaneously by reduction of Carbonate with magnesium under shock wave loading.In addition,by adding ammonium nitrate or urea to the reaction system,nitrogen-doped graphene material was formed in this one-step shock treatment.The recovered samples were characterized using various techniques such as transmission electron microscopy,scanning electron microscopy,Raman spectroscopy and X-ray photoelectron spectroscopy.Shock-synthesized nitrogen-doped graphene material was demonstrated to act as a metal-free electrode with an efficient electrocatalytic activity and long-term operation stability for the oxygen reduction reaction via two-and four-electron pathways in alkaline fuel cells.
