Synthesized and characterization of Ce2(MoO4)2(Mo2O7)/MoO3 nanocomposites with Schiff-base ligand assistance as possible electrode materials for electrochemical energy storage

Abstract

Transition metal oxides, which can deliver a cooperative impact through electrochemical processes, are now being investigated extensively as potential electrode materials for next-generation storage devices. Ce2(MoO4)2(Mo2O7)/MoO3 composites were created using hydrothermal technique aided by Schiff-base ligands in the low temperature and short time. Synthesis of composites in the presence of different ligands led to design different morphologies such as particles, plates, flower-shaped and spheres. The produced sample functions as an active component of the electrochemical energy storing arrangement, which is included of a KOH electrolyte and a three-electrode cell. Morphology affects both the durability of the compounds in the designed working electrode and the kinetics of the electrochemical process. Although, capacitance of Ce2(MoO4)2(Mo2O7)/MoO3 composites was considered at different morphologies for determining optimal performance. Results show ideal sample prepared in the presence of H2acacmda with microsphere morphology and surface area of 12.83 m2g−1 which demonstrates maximum capacity of 246 mAhg−1.
