Plasma-etched Ti2O3 with oxygen vacancies for enhanced NH3 electrosynthesis and Zn–N2 batteries

Abstract

The sustainable production of NH3 through an ambient electrocatalytic N2 reduction reaction (NRR) requires the ingenious design of efficient electrocatalysts. Herein, plasma-etched Ti2O3 with oxygen vacancies (OV-Ti2O3) is reported as an active and stable electrocatalyst for NRR. The resulting OV-Ti2O3 catalyst exhibits outstanding N2 fixation performances in 0.1 M HCl with the maximum NH3 yield and faradaic efficiency of up to 37.24 μg h−1 mgcat.−1 and 19.29%, respectively. Additionally, a rechargeable aqueous Zn–N2 battery with an OV-Ti2O3 cathode was assembled to deliver a power density of 1.02 mW cm−2 and an NH3 yield of 4.3 μg h−1 mgcat.−1, outperforming reported Zn–N2 batteries.
