Synergistic Effect of Reduced Graphene Oxide and BaLaMnFeO6 in BaLaMnFeO6/rGO Composite on Electrochemical Behavior

Abstract

Perovskite oxides, with their diverse properties and versatile structures, have emerged as promising materials for electrochemical energy storage devices. The X‐ray diffraction patterns of both BaLaMnFeO6 (BLMFO), and its reduced graphene oxide (rGO) composite, synthesized through solvothermal process, revealed the formation of rhombohedral structure with space group R‐3C (no. 167). The estimated lattice parameter are a = 5.59 Å, b = 5.59 Å and c = 13.60 Å. As per the Brunauer–Emmett–Teller (BET) analysis, BLMFO/rGO composite (≈32.12 m2 g−1) exhibited a higher specific surface area than pristine BLMFO (≈11.85 m2 g−1), which has been attributed to the enhanced porosity resulted due to addition of rGO. The specific capacitance of pristine BLMFO and composite BLMFO/rGO is found to be 170.7 and 330.2 Fg−1, respectively, at the current density 1 Ag−1. The present investigation on the solvothermal synthesis and electrochemical analysis of BLMFO perovskite and its rGO composite, demonstrates potential for energy storage application.
