Electrochemical hydrogen storage capacities of sol-gel synthesized Dy3Fe5O12/DyFeO3 nanocomposites: Schiff-base ligand-assisted synthesis and characterization

The nanostructured multiferroic Dy-Fe-O electrode materials for hydrogen storage request are synthesized via H2Salbn assisted sol-gel procedure. H2Salbn Schiff-base ligand plays the dual role of capping agent and fuel. The synthesis parameters affect the purity of obtained samples to form pristine DyFeO3, DyFeO3/Dy3Fe5O12 and Dy3Fe5O12/DyFeO3 compounds. Electrochemical attributes of resulting products are discovered by CV and charge-discharge chronopotentiometry techniques. The discharge capacity for DyFeO3/Dy3Fe5O12 nanocomposites by a high amount of DyFeO3 in the composite texture measured 447 mAhg−1 at a current of 1 mA. However, the discharge capacity for nanocomposites of Dy3Fe5O12/DyFeO3 with a high amount of Dy3Fe5O12 in the composite texture is considered about 257 mAhg−1 at a current of 1 mA. According to the found consequences, the DyFeO3/Dy3Fe5O12 nanocomposites verify appropriate capacity as the probable and capable active material for hydrogen storage policies.
