Abstract

Multilayer graphene was synthesized by chemical vapor deposition from mixture of naphthalene/ methanol with ratios (1.5 g: 100 m L) respectively at ambient pressure and nitrogen as carrier gas with two different flow at 700ᵒ. The active sites for growth was Ferrocene with thickness reach to125 μm. The product was characterized by Raman spectroscopy, scanning electron microscopy, and Energy Dispersive X-Ray Analysis. The analysis shows that high flow of carrier gas (250 cm3/min) was succeeded to produce graphene multilayers while the ether (100 cm3/min) witnessed many tubular structure in addition to graphene layers.Multilayer graphene was synthesized by chemical vapor deposition from mixture of naphthalene/ methanol with ratios (1.5 g: 100 m L) respectively at ambient pressure and nitrogen as carrier gas with two different flow at 700ᵒ.
