Cover Feature: Structural Features of Porous CoFe Nanocubes and Their Performance for Oxygen‐involving Energy Electrocatalysis (ChemElectroChem 18/2020)

Abstract

The Cover Feature shows that microporous CoFe‐200 nanocubes (mean pore diameter, d≈1.2 nm) are beneficial for the oxygen evolution reaction (OER) because of the improved active site densities despite their larger diffusion path, whereas microporous/mesoporous CoFe‐550 (d≈35.6 nm) favors the oxygen reduction reaction (ORR) by enabling the mass transport of oxygen through the catalyst.
