Bimetallic Metal-Organic Frameworks enable tandem catalysis for Efficient Electrocatalytic Nitrate Reduction and Zn-NO 3 -Batteries

Abstract

A bimetallic Cu/Fe-NDC pre-catalyst enables tandem catalysis to suppress nitrite release, achieving a 92.5% NH3 Faradaic efficiency and a yield of 3.8 mg h-1 mgcat-1. The assembled Zn–NO3- battery delivers a peak power density of 12.5 mW cm-2, demonstrating its potential for nitrate remediation and power output.
