Abstract

İndirgenmiş grafen oksit (rGO) ve grafen oksit (GO) birçok araştırma alanında popülerlik kazanmaktadır. rGO sentezi, grafitin oksidasyonu ve GO'nun indirgenmesi olmak üzere iki faklı aşamadan oluşan aşağıdan yukarı üretim esasına dayanır. rGO yapısının özelliklerini, hammadde olarak kullanılan GO, indirgeme ajanları ve proses türü belirlemektedir. GO'yu rGO'ya indirgemek için farklı kimyasal ajanlar kullanılır ve bunlar arasında hidrazinin en güçlü ve etkili ancak en toksik ajan olduğu bilinmektedir. Bu çalışmada rGO sentezi yeşil ve kimyasal olmak üzere iki farklı yaklaşım ile indirgeyici ajan olarak L-askorbik asit (C Vitamini) ve sodyum ditiyonit (Na2S2O4) kullanılarak gerçekleştirilmiştir. GO, toksik sodyum nitrat kullanılmadan Modifiye İyileştirilmiş Hummers Yöntemi ile sentezlenmiştir. İndirgenen ürünler, FTIR, XRD ve SEM / EDS ile incelenmiştir. Sonuçlar, farklı indirgeyici ajanların, 0.34 nm tabakalar arası mesafeye sahip benzer rGO-Na2S2O4 ve rGO-LAA yapılarının sentezlediğini ayrıca bu yapıların sırasıyla % 14.27 ve % 12.24 oksijen içerdiğini göstermiştir.

Abstract

Reduced graphene oxide (rGO) and graphene oxide (GO) are gaining popularity among many research areas. rGO synthesis is based on bottom-up production, which consists of two different stages: the oxidation of graphite and the reduction of GO. The properties of rGO structure are determined by GO used as raw material, reducing agents and the type of process. Different chemical agents are used to reduce GO to rGO and among these, hydrazine is known to be the strongest and effective, but the most toxic agent.
In this study, the rGO structure synthesized using sulfur-containing sodium dithionite (Na2S2O4) was compared with the rGO structure synthesized by L-ascorbic acid (Vitamin C) agent in terms of layer number, elemental analysis and crystal structures, and It has been observed that Na2S2O4 may be a good is a good alternative. to reduce GO. GO was synthesized by Modified Improved Hummers method without using toxic sodium nitrate. The reduced products were examined by FTIR, XRD and SEM/EDS. Results showed that different reducing agents synthesized similar rGO-Na2S2O4 and rGO-LAA structures with 0.34 nm interlayer space also they included % 14.27 and %12.24 of oxygen respectively.
