Facile synthesis of efficient Co₃O₄nanostructures using the milky sap of<i>Calotropis procera</i>for oxygen evolution reactions and supercapacitor applications

Abstract

, the reduction in the optical band gap and the fast charge transfer rate. These surface, structural, and optical properties were induced by reducing, capping, and stabilizing agents from the milky sap of CP. The obtained results of OERs and supercapacitor applications strongly recommend the use of the milky sap of CP for the synthesis of diverse efficient nanostructured materials in a specific application, particularly in energy conversion and storage devices.
