Abstract
The oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) for dual-functional non-precious metal
electrocatalysts are promising alternatives for Pt/Ru-based materials in rechargeable zinc-air batteries (ZABs).
However, how to achieve dual-functional oxygen electrocatalytic activity on single-component catalysts and
identify the sites responsible for ORR and OER still face many challenges. Herein, an efficient and stable dual-
functional electrocatalyst is fabricated by a two-step hydrothermal method with iron phthalocyanine (FePc) π-π
stacking on nickel-iron selenide layered hydroxide derivatives (Se/Ni Se /Fe O ). The as-prepared multi-
3 4 3 4
component catalyst (named as FePc/Se@NiFe) exhibits better oxygen electrocatalytic properties than Pt/Ru-
