The high cost and elemental scarcity of precious metals has triggered a search for non-noble-metal catalysts for the oxygen evolution reaction (OER) process. Herein, with the assistance of metal organic frameworks (MOFs), a core/shell ZnCo2O4/ZnO nanoarray with an amorphous carbon protecting layer, grown on carbon fiber, was in situ topologically generated. The resulting catalyst shows much enhanced OER performance under alkaline condition, requiring as low as 279 mV of overpotential to reach 10 mA cm-2 current density. Our work may open up a new way for exploiting MOF-derived non-noble-metal electrocatalysts for various electrochemical applications.

Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
