Abstract

A self-supported NiTeO₃ perovskite is made by deploying an extended hydrothermal tellurization strategy with a restricted Te content, which was found to be exceptionally active towards the oxidation of water and methanol and the reduction of water in 1.0 M KOH where it delivered −10 mA cm⁻² at just −1.54 V for a full cell featuring MOR‖HER.
