Zn–Air Batteries: Trifunctional Electrocatalysis on Dual‐Doped Graphene Nanorings–Integrated Boxes for Efficient Water Splitting and Zn–Air Batteries (Adv. Energy Mater. 14/2019)

In article number 1803867 by Chuanxin He and co-workers an easy yet robust route is developed to craft N, O-codoped graphene-integrated boxes by employing hybrids containing polymers and Prussian blue analogue cubes as precursors. Benefiting from the hierarchically porous nanostructures and highly active N, O-codoped graphene, the resulting electrocatalysts display excellent performance in overall water splitting and Zn–air batteries.
