Cover Feature: Engineering Amorphous/Crystalline Structure of Manganese Oxide for Superior Oxygen Catalytic Performance in Rechargeable Zinc–Air Batteries (ChemSusChem 15/2022)

The Cover Feature shows a desert, which represents the serious energy problems encountered. The sand dune is also the representative of the energy barriers in the oxygen reduction and evolution reactions in Zn–air batteries. Efficient catalysts can effectively reduce the reaction energy barrier and accelerate the reaction. The road is green, leading to the oasis in the desert. The road is made by the prepared catalysts consisting of dark-green areas (crystalline regions) and light-green areas (amorphous regions). More information can be found in the Research Article by Z.
