Amorphous/crystalline heterointerface perovskite oxide electrocatalyst

High power and durable zinc-air battery

Nb and F co-doping with alkali treatment induces in situ exsolution to form amorphous/crystalline heterointerfaces, synergistically boosting OER and ORR kinetics for high-performance zinc-air batteries.
