Bu çalışmada, elektrokimyasal bir teknik kullanılarak ilk defa tek kapta indiyum oksitle indirgenmiş grafen oksit (In2O3-rGO) kompozitleri üretildi. Grafen oksit (GO) miktarının kompozit yapının kompozisyonu ve morfolojisi üzerindeki etkisi incelendi. Bu amaçla, GO ve In3+ iyonları içeren elektrolit çözeltileri farklı hacim oranlarında karıştırıldı. Biriktirmeler farklı elektrolit kompozisyonlarında sabit potansiyelde gerçekleştirildi. Farklı deneysel parametreler altında hazırlanan kompozit yapıların karakterizasyonları X-ışını kırınım spektroskopisi (XRD), X-ışını fotoelektron spektroskopisi (XPS), Raman spektroskopisi ve alan etkili taramalı elektron mikroskobu (FESEM) teknikleri kullanılarak incelendi. En iyi kompozisyona sahip In2O3-rGO kompozitinin hacimce 1:1 GO:In3+ elektrolit oranında elde edildiği sonucuna varıldı.

Influence Of Graphene Oxide Amount on The Structure and Morphology of In2O3-Reduced Graphene Oxide Composite Film

Öz

In this study, indium oxide-reduced graphene oxide (In2O3-rGO) composites were produced in one-pot using an electrochemical technique for the first time. The effect of graphene oxide (GO) amount on the composition and morphology of the composite structure was investigated. For this purpose, electrolyte solutions containing GO and In3+ ions were mixed at different volume ratios. Deposits were carried out at constant potential in different electrolyte compositions. The characterizations of the composite structures prepared under different experimental parameters were investigated using X-ray diffraction spectroscopy (XRD), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, and field effect scanning electron microscopy (FESEM) techniques. It was concluded that the In2O3-rGO composite with the best composition was obtained in 1:1 GO: In3+ electrolyte by volume.
