Electrochemical hydrogen storage capabilities of Li2Co2 (MoO4) 2 nanostructures: Schiff base-assisted synthesis and characterization

Abstract

In light of the fact that transition metal oxides can have a synergistic effect during electrochemical operations, they are now the subject of extensive research as potential electrode materials for the subsequent group of storage strategies. Effect of ligand ratio on the morphology and purity of samples was investigated and analyzed using XRD, SEM and TEM data. The purity of all samples shows the formation of Li2Co2(MoO4)2 phase with a partial phase of CoMoO4, in the hydrothermal synthesis. Diverse morphology of rods, tiny rods and flower-shaped structures were observed in the presence of different ratios of ligands. Elemental and functional groups analysis were conducted using EDS and FT-IR examination. In the presence of Schiff-base ligand, the Li2Co2(MoO4)2 samples that were created act as a functional component of the electrochemical energy storage classification. The electrochemical system comprises a KOH electrolyte and a three-electrode cell for chronopotentiometry charge-discharge test. Both the stability of the materials, as well as the kinetics of the electrochemical procedure, are affected by the form of the components that are included inside the working electrode. In order to determine which parameters required the most efficient performance, the capacity of the synthesized Li2Co2(MoO4)2 was examined under various circumstances. A supreme capacity of 450 mAhg−1 was shown by the findings after 15 cycles were completed.
