Exploring economically efficient electrocatalysts with robust bifunctional oxygen conversion catalytic activity and designing appropriate structures are essential to realize ideal zinc-Air batteries with high energy density and long lifespan. Two-dimensional metallic state Co3FeN nanosheets with a holey-structured architecture are designed and shown to exhibit enhanced catalytic properties owing to the complete exposure of the atoms in the large lateral surfaces and in the edges of pore areas, together with the lowest OH∗ adsorption energy on exposed surfaces due to bimetallic synergistic effects. Meanwhile, this porous architecture can not only accelerate electron transportation by its metallic state highly oriented crystallized structure, …

Both the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) are crucial to water splitting, but require alternative active sites. Now, a general pelectron- assisted strategy to anchor single-atom sites (M=Ir, Pt, Ru, Pd, Fe, Ni) on a heterogeneous support is reported. The Matoms can simultaneously anchor on two distinct domains of the hybrid support, four-fold N/C atoms (M@NC), and centers of Co octahedra (M@Co), which are expected to serve as bifunctional electrocatalysts towards the HER and the OER. The Ir catalyst exhibits the best water-splitting performance, showing a low applied potential of 1.603V to achieve 10 mAcm@2 …
