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