Self-powered NH₃ synthesis by trifunctional Co₂B-based high power density Zn–air batteries

Abstract

An approach to eliminate the use of external power to drive NH 3 synthesis is presented. A trifunctional Co 2 B catalyst enables high power density ZABs (500 mW cm −2 ) to drive NH 3 synthesis with a production rate of 1.048 mg h −1 mg cat. −1 after 2 h.
