Abstract

In this study, a nanocomposite material consisting of copper bismuthate (CuBi2O4) and reduced graphene oxide (ERGO) (CuBi2O4/ERGO) was successfully synthesized on the nickel (Ni) foam electrode surface using a new one-pot electrochemical technique. A mixture solution containing Cu+2, Bi+3, and graphene oxide (GO) was used as the solution medium. Firstly, the hydroxide species were deposited on Ni electrode in the solution medium, in which oxygen gas was passed. Afterward, thermal annealing was performed and the hydroxide species were converted to the oxide form. Electrochemically synthesized CuBi2O4/ERGO modified electrodes were characterized using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Raman, field emission scanning electron microscopy (FE-SEM), and energy dispersion spectroscopy (EDS) techniques. The characterization processes showed that the nanocomposite contains both CuBi2O4 and ERGO structures together.

Özet

Bu çalışmada, bakır bizmutat (CuBi2O4) ve elektro-indirgenmiş grafen oksitten (ERGO) oluşan nanokompozit (CuBi2O4/ERGO) materyal tek kapta yeni bir elektrokimyasal teknik kullanılarak nikel (Ni) köpük elektrot yüzeyinde başarıyla sentezlenmiştir. Çözelti ortamı olarak Cu+2, Bi+3 ve grafen oksit (GO) ihtiva eden çözelti karışımı kullanılmıştır. Öncelikle oksijen gazı geçirilen çözelti ortamında Ni köpük elektrot yüzeyinde hidroksit türleri depozit edilmiştir. Sonrasında termal tavlama yapılarak oksit formuna dönüşüm sağlanmıştır. Elektrokimyasal olarak sentezlenen CuBi2O4/ERGO modifiye elektrotlar X-ışını kırınımı (XRD), X-ışını fotoelektron spektroskopisi (XPS), Raman, alan emisyonlu taramalı elektron mikroskobu (FE-SEM) ve enerji dağılım spektroskopisi (EDS) teknikleri kullanılarak karakterize edilmiştir. Yapılan karakterizasyon işlemleri nanokompozitin hem CuBi2O4 hem de ERGO yapısını bir arada içerdiğini göstermiştir.
