Preparation and Characterization of Graphene Doped Molybdenum Trioxide/Manganese Oxide Ternary Nanocomposite for Supercapacitor Performance

Synergistic Analysis of Hydrothermally Synthesized PANI-GO: MnO2/MoO3 Nanocomposites for Enhanced Structural and Supercapacitor Performance

“…The cyclic voltammetry (CV) curves show the electrochemical double layer and slight pseudo-capacitive behavior. At the lower scan rate, the curves were narrow rectangular shapes, whereas at the higher scan rate, their structures deformed and got broader, which demonstrated fast electrochemical ion intercalation at the lower scan rate and slower ion intercalation at the higher scan rate [16]. This is attributed instability of electrode materials at a higher scan rate.…”

“…It aligns with the generation of polaronic emeraldine from the leucoemeraldine phase, while the second redox peak arises from the transformation of polaronic emeraldine into the bipolaronic pernigraniline phase [32]. The remarkable electrochemical performance of the ternary PANI-GO:MnO2/MoO3 composites was a result of the harmonious synergy among all three components, leading to a well-arranged nanostructure [16,17]. Furthermore, PANI can substantially enhance pseudocapacitance, thereby contributing to enhanced overall capacitance.…”

“…The resulting precipitate was then washed multiple times with ethanol to remove impurities. In sample 2, 0.1 mol of polyaniline was combined with a ternary composite of GO:MnO2/MoO3/MnO2 (graphene oxide) as described in our previous report [16,17]. Similarly, samples 3, 4, and 5 were prepared with 0.3 mol, 0.5 mol, and 0.7 mol of polyaniline, respectively, along with the same ternary composite.…”
