Abstract

Back cover image: Electrocatalytic selective oxidation of amines to imines is an attractive way to produce nitrile compounds, but it is limited by inefficient catalysts. Herein, we apply a oxyhydroxide layer formed on top of iron-doped layered nickel phosphorus trisulphides (Ni1-xFexPS3) to induce oxidation of benzylamine (BA). Structural and surface chemical characterizations during the electrocatalytic process combined with calculations reveal that Ni1-xFexPS3 undergoes surface reconstruction under alkaline conditions to form metal oxyhydroxide/phosphorus trichalcogenide (NiFeOOH/Ni1-xFexPS3) heterostructure. The heterointerface facilitates BA oxidation with a low onset potential of 1.39 V and Faradaic efficiency of 53% for benzonitrile synthesis. The NiFeOOH/Ni1-xFexPS3 heterostructure off ers optimum free energy for BA adsorption and benzonitrile desorption, resulting in promising benzonitrile synthesis. In article cey2.672, Wu et al.
