Atomic Engineering of Single Crystals: Designing High-Efficiency Bifunctional Co/Fe Single-Atom and Alloy Catalysts for Zinc-Air and Zinc-Ion Batteries.
Single-crystalline metal oxides offer well-defined coordination environments to suppress metal migration, yet their application as precursors for bifunctional oxygen electrocatalysis remains limited. In this study, single-crystal x-ray diffraction and Fourier-transform infrared spectroscopy were employed to confirm the...
