Abstract

High-performance catalysts are required in various energy storage and conversion systems. In this work, hierarchical Ni-Fe-Mo trimetal nitride nanotubes (NTs) as highly efficient, low-cost, robustly stable, multifunctional catalysts through room-temperature Fe incorporation and subsequent thermal treatment for full water splitting and Zn-air batteries are fabricated. The two-electrode electrolyzer assembled from the NTs delivers a current density of 10 mA cm−2 at 1.513 V, outperforming the precious metal IrO2|Pt couple and state-of-the-art bifunctional catalysts. Furthermore, two all-solid-state Zn-air batteries with the hierarchical NT air cathode in series can power 55 red light-emitting diodes with excellent operation stability, at the same time as the electrolyzer based on the hierarchical NTs.
