“…The Cu substitution in ZnMn 2 O 4 lattice improved the electronic structure, including the electrochemical active surface area and the surface roughness toward the enhanced OER activity. [80] Interestingly, Zhao et al controlled the defects in CoMn 2 O 4 by regulating the electronic structure via Zn ion doping. Comparatively, the Zn-CoMn 2 O 4 -1.5 (molar concentration of zinc nitrate) showed efficient overall water splitting with the overpotential of 146 mV at −10 mA cm −2 and 280 mV at 50 mA cm −2 for HER and OER, respectively.…”

Spinel manganates (AMn2O4; A = Co, Ni, Cu, Zn, and Fe; collectively referred to as AMO) are promising electrode materials for water electrolyzers, pseudocapacitors, and batteries owing to their inherent advantages such as valence variability, high catalytic activity, conductivity, stability, low‐cost, and environmental friendliness. Nanostructured materials, with a large surface area and short ion diffusion length, offer great potential for achieving enhanced electrochemical performance. This review summarizes spinel manganates with various nanostructured morphologies and discusses the impact of the structure and composition on the electrochemical performance. The review demonstrates that nanostructured spinel manganates with preferred A‐site cation significantly improve the thermodynamics and electrochemical reaction kinetics at solid–liquid and solid–solid interfaces. Notably, faceted, hollow, 1D nanostructured CoMn2O4 and its nanocomposites (CoMn/CoMn2O4 and NiMn2O4/C) exhibit outstanding electrochemical performance. The review also provides an overview of the importance of energy conversion and storage, and the advantages of spinel manganates as electrode materials. Additionally, the review describes feasible methods of synthesizing AMO nanostructures and nanocomposites. The insights provided in this review are expected to contribute to the synthesis of spinel manganates with desired morphologies and compositions, enabling the future development of efficient electrode materials for energy conversion and storage devices.
