Abstract

Abstract : The Cover Feature shows a new approach for water electrolysis, by rethinking the reaction at the anode: n ‐butyronitrile from n ‐butylamine is selectively produced as an easily retrievable valuable product, instead of oxygen gas. We study industrially relevant oxygen evolution reaction catalysts, CoO x, NiFeO x, and NiO x . They all show lower anodic potentials in the presence of n ‐butylamonium sulfate, without poisoning the active sites of Pt electrocatalyst for the hydrogen evolution electrode side. The highest activities were observed for NiO x thin‐film electrodes.
