Inspired by the synergistic effect of hybrid catalyst, the bifunctional catalyst NSC@Co 3 O 4 is designed using Nd 0.5 Sr 0.5 CoO 3 (NSC) perovskite and Co 3 O 4 spinel and is synthesized via the simple technique (i.e. infiltration). At the interface of NSC and Co 3 O 4 , the electronic and structural reconstructions enhanced the catalytic activity for oxygen reduction/evolution reactions (ORR/OER). The designed cover image depicts the morphology (nanosized Co 3 O 4 distributed on NSC) and the interfacial effect of the catalyst.
