Cover Feature: Hierarchical Fe Doped Co Oxide/Hydroxide Nanosheet Arrays as Highly Efficient Oxygen Evolution Catalysts Prepared by Hydrothermal Etching of FeCo Prussian Blue Analogue (Eur. J. Inorg. Chem. 17/2022)

Abstract

The Cover Feature shows the oxygen evolution process catalyzed by a hierarchical FeCo oxide/hydroxide catalyst grown on Ni foam, which is prepared by a hydrothermal etching method with FeCo Prussian blue analogue as precursor. Spectroscopic and microscopic investigation demonstrated that the electronic structure of the surface was optimized by Fe doping, and more active sites were exposed with a self-standing 2D/2D hierarchical structure. The harmony of these two aspects contributes greatly to the outstanding OER catalytic activity. More information can be found in the Research Article by R. Xiang and co-workers.
