Structural, Dielectric, and Energy Storage Properties of Citric Acid and Ethylene Glycol Assisted Hydrothermally Synthesized Y2FeCoO6

“…[ 3–5,8 ] Here, the hydrothermal process has been used, as it precisely controls crystallite size, morphology, and ensures atomic level mixing of various elements at relatively lower temperatures in comparison to other techniques, which, in turn, leads to enhancement of electrochemical behavior because of the larger specific surface area of the products. [ 6,14,16 ] To our knowledge, this is the first report on the hydrothermal synthesis and electrochemical characterization of Y 2 FeCoO 6 . Here, the structural, morphological, dielectric, and electrochemical behavior of synthesized Y 2 FeCoO 6 double perovskite oxide has comprehensively been investigated.…”

“…[ 1,2 ] The investigation on electrochemical energy storage application of this class of materials has surged recently. [ 3–6 ] The engineering of various elements substitution such as Ti, Fe, Co, Ni, Cu, etc., at M lattice sites has attracted research interests in these materials, as multi‐oxidation states of transition metals lead to excellent electrochemical behavior. [ 3–7 ] Furthermore, the room temperature giant relative permittivity and low loss factor of such materials, viz., Ba 2 PrRuO 6 , La 2 MnCoO 6 , La 2 FeCoO 6 , Sr 2 CoNbO 6 , Ho 2 CdTiO 6 , Pr 2 CoTiO 6 , Y 2 CoMnO 6 make them very useful for energy storage application.…”

“…Recently, significant research has been conducted on double perovskite oxide materials to understand their various electrochemical, magnetic, and electronic properties. [ 1–6 ] Electrochemical and magnetic behavior of several double perovskites, e.g., Y 2 FeMnO 6 , Y 2 NiMnO 6 , Y 2 CoMnO 6 , and Y 2 CrMnO 6 with yttrium at R position have been studied. [ 12–15 ] A report on Y 2 NiMnO 6 double perovskite revealed the enhancement in specific capacitance from 17.4 to 77.76 F g −1 for bulk material synthesized by sol–gel method to nanowire synthesized by the hydrothermal process.…”
