Synergistic electro-catalysis of Pd/PDO nanoparticles and Cr(III)-doped NiCo 2 O 4 nanofibers in aprotic Li-O 2 batteries
In this work we discuss the co-catalysis in aprotic Li-O 2 batteries of C-free nanostructured mixed oxide electrodes decorated by Pd/PdO core/shell nanoparticles. A Cr(III) doped NiCo 2 O 4 material has been grown hydrothermally on an open Ni-mesh. Palladium nanoparticles have been synthesized by pulsed lased ablation in liquid acetone in the fs regime and deposited by drop casting onto the surface of the nanostructured mixed oxide electrodes. The resulting electrodes have been calcined at 300 ◦ C.
