The frontispiece shows the dependence of the peak current for the oxygen reduction reaction (ORR) on PdCo catalysts on nominal Co content, the highest ORR actvity, observed for an atomic composition of 25 % Co, being ascribed to alloying effects on the specific activity. The Minireview by E. Antolini on page 765 ff. outlines the effect of structural characteristics, such as degree of alloying, particle size, and Pd segregation on the alloy surface to form a coreshell system, on the ORR activity of PdCo catalysts.
