Frontispiece: Topotactic Synthesis of Porous Cobalt Ferrite Platelets from a Layered Double Hydroxide Precursor and Their Application in Oxidation Catalysis

Abstract

Holey hexagonal platelets of cobalt ferrite, CoFe2O4, can be obtained by co‐precipitation and thermal decomposition of a layered double hydroxide (LDH) precursor. These particles are single crystalline and porous at the same time and show a topotactic relationship with the precursor. They are active as catalyst in alcohol oxidation and as electrocatalyst in the oxygen evolution reaction showing a clearly different behavior than commercial powder likely due to their unique microstructure. For more details, see the Communcation by T. Lunkenbein, M. Behrens et al. on page 12443 ff.
