Abstract
Graphene oxide (GO) was modified by 4,4â²-methylenedianiline to form a nanocomposite material (GO-amine). Materials were characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis, derivative thermogravimetric and field emission scanning electron microscopy. The electrochemical behavior of modified carbon paste electrode (CPE) with GO-amine (GO-amine/CPE) was studied by electrochemical methods. The results showed which GO-amine/CPE catalyzes oxygen evolution reaction in alkaline media with an onset potential of 0.4 V (vs. Ag|AgCl|KCl3M), showing a synergistic effect between GO and amine nanocomposite. The high electrochemical stability confirmed the improved electrocatalytic performance of GO-amine. This study affords us a GO-amine based electrocatalyst with high performance and strong durability under alkaline conditions, which can be applied to energy conversion and storage.
