Influence of the Synthesis Route on the Properties of Hybrid NiO–MnCo₂O₄–Ni₆MnO₈ Anode Materials and their Electrochemical Performances

Abstract

New materials with different morphologies, nanostructures, and components can have structural advantages for application in materials science. Multicomponent‐active hybrid nanostructured materials are among the best candidates for application in electrode materials. Spray pyrolysis and solvothermal synthesis are two popular methods for the preparation of multicomponent‐active hybrid nanostructured materials. In this study, the two types of NiO‐MnCo2O4‐Ni6MnO8 hybrid anode materials for use in lithium‐ion batteries were synthesized by two different methods (spray pyrolysis and solvothermal synthesis), and the differences in their physical and electrochemical properties were compared. The two types of anode material exhibited the same hierarchical hybrid composition, but some different physical characteristics, which affected their electrochemical performance.

Progress in the Preparation of Metal Oxide Electrodes for the Electrochemical Treatment of Organic Wastewater: A Short Review

“…MOx: active sites on the anode surface. Due to the differences in the structure and physical and chemical properties of different active electrode materials [42][43][44], the efficacy of these materials in the electrocatalytic oxidation of wastewater varies. In the process of electrochemical treatment, the selection of the active electrode must usually account for the following points: the surface of the active electrode needs to have excellent catalytic performance [45][46][47][48], which means that the surface of the electrode should have a large enough specific surface area to form a large number of active sites and promote the redox reaction.…”
