Facile and ecofriendly green synthesis of CoO/MgO-SiO composites towards efficient asymmetric supercapacitor and oxygen evolution reaction applications.

The development of low-cost, eco-friendly, and earth-friendly electrode materials for energy storage and conversion applications is a highly desirable but challenging task for strengthening the existing renewable energy systems. As part of this study, orange peel extract was utilized to synthesize a magnesium oxide-silicon dioxide hybrid substrate system (MgO-SiO) for coating cobalt oxide nanostructures (CoO) hydrothermal methods. A variety of MgO-SiO compositions were used to produce CoO nanostructures.
