Construction of CuFe layered double hydroxide mediated by Zn vacancies for high-efficiency electrocatalytic conversion of nitrate to ammonia.

Abstract

This work introduces zinc vacancies to engineer the surface structure of CuFe layered double hydroxide, which realizes the high-efficiency electrocatalytic reduction of nitrate waste to useful ammonia. This is attributed to the increase in active sites, electron cloud redistribution and facilitated charge transfer via the introduction of zinc vacancies.
