ملخص المقالة :
Graphene films were fabricated over synthesized MCM-41 nanocatalyst by chemical vapordeposition method, and the reaction was carried in atmospheric pressure at 750˚C. Acetylenegas used as a carbon precursor and the synthesis reaction took place in hydrogen atmosphere.Mesoporous MCM-41 was synthesized at room temperature, using wet chemical method. Thesynthesized metal free catalyst was characterized by XRD and N2 adsorption isotherms. Thecatalytically synthesized graphene layers were characterized by Raman spectroscopy, scanningelectron microscopy (SEM), and transmission electron microscopy (TEM). The results indicatedthat the favorable effect of MCM-41 with high BET surface area (908.76 m2/g) as an activemetal free nanocatalyst for fabricating graphene layers with high level of purity and homogeneity.Because of simplicity, easy purification, and high yield of graphene synthesis offered bythis method, it is possible to use it in larger scales.
