Facile synthesis and electrochemical performance of double perovskite oxide Y₂CuMnO₆ for energy storage application

The present work unveils the facile chemical synthesis of novel double perovskite Y₂CuMnO₆ by a sol-gel route. The double perovskite Y₂CuMnO₆ exhibits a monoclinic structure with P2_1/n symmetry. The morphology has been observed by scanning electron microscope. The chemical bonds analysis of double perovskite Y₂CuMnO₆ has been carried out using Fourier Transform Infrared spectroscopic technique. The electrochemical behavior of double perovskite has been studied in 1M Na ₂SO₄ aqueous solution as an electrolyte, at various scan rates ranging from 2 mV/s to 100 mV/s. The CY curve has rectangular loops that reveal that double perovskite Y₂CuMnO₆ possesses electric double layered capacitor (symmetric) behavior. Further, this behavior has been verified by Galvanostatic Charging Discharging (chronopotentiometry technique). (author)
