Rationally Designed Mn ₂ O ₃ –ZnMn ₂ O ₄ Hollow Heterostructures from Metal–Organic Frameworks for Stable Zn‐Ion Storage

Heterostructured Mn2O3–ZnMn2O4 hollow octahedrons (MO–ZMO HOs) are rationally designed and fabricated through a two-step metal–organic framework-engaged synthetic approach. With the structural and compositional advantages, the MO–ZMO HOs electrode shows efficient Zn-ion storage performance in terms of high reversible capacity, excellent rate capability and ultra-stable cycle life.
