•The peroxidase mimetics and ORR activity of PdPt NWs and NSs were investigated.•PdPt NSs possessed much better peroxidase mimetics than that of PdPt NWs.•PdPt NSs exhibited more advantageous onset potential and higher ORR activity.•PdPt NWs presented higher limiting current density.
A comparative study on bimetallic alloy nanomaterials, with different dimensions (i.e., 1D nanowires and 3D nanosponges), of peroxidase mimetics and as enhanced catalysts for oxygen reduction reaction was performed. The synthesized PdPt nanosponges possessed much better oxidase and peroxidase mimetics than those of PdPt nanowires. In addition, nanosponges exhibited more advantageous onset potential and higher ORR specific activity, while nanowires presented higher limiting current density.
