Enhanced electrocatalytic oxygen evolution reaction of network structured Polypyrrole-NaBiO2 nanocomposite in alkaline media
When it comes to the ability of the water splitting process to create hydrogen, the challenging dynamics of the water-oxidation reaction (WOR) provide a substantial impediment. So, in order to start both hydrogen and oxygen production during water electrolysis, efficient catalysts are needed. Herein, we report the development of NaBiO2@PPy nanocomposite capable of oxygen evolution reactions (OER) in alkaline medium. The fabricated NaBiO2@PPy nanocomposite and its individuals are characterized via various techniques to confirm the structural, elemental, textural, and morphological characteristics. This material produces a current density of 10 mA/cm2 for oxygen evolution comparatively at low overpotentials of 227 mV and maintains its stability for up to 50 h. Furthermore, the fabricated NaBiO2@PPy nanocomposite also shows less Tafel slope of 30.8 mV/dec. Therefore, this catalytic material would be a good option for creating a cost-effective, and environmentally friendly alkaline medium. In order to enhance the performance of water electrolysis, this work offers a revolutionary designed material and electrode fabrication method for future applications.
