چکیده
|
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 700 °c. 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.
