Abstract : In this work, graphene nanosheets (GN) have been successfully prepared under lower carbonization temperature by using the layered compounds CoAl-LDH. A series of characterizations such as XRD, FTIR, Raman TEM, SEM, EDX, XPS and UV–vis were used to verify the formation of graphene nanosheets in the layered structure of CoAl-LDH. It can be concluded that the Co element of layered double hydroxide acted as the catalytic centers in the formation of graphene nanosheets.
