Hollow PdO-Co3O4 nano-dodecahedrons with moderate catalytic activity were designed as electrocatalysts for Li-O2 batteries, and not only reduce the overpotentials effectively but also improve the reversibility of the ORR and OER, and cycle for more than 90 cycles stably with extremely low overpotentials.
