Our new paper, submitted to ACS Appl. Eng. Mater., has been selected by the editors to be featured on the cover page. The manuscript, entitled ‘Cobalt-/Copper-Containing Perovskites in Oxygen Evolution and Reduction Reactions,’ discusses the electronic properties of perovskite oxides as bifunctional catalysts that play a significant role in their activity in oxygen evolution and reduction reactions. These properties can be easily tuned by adsorbed molecules on the surface, primarily shifting the Fermi levels to lower energies, thus enhancing their catalytic activity.
