Herein, six metalloporphyrins (M = Fe, Co, Ni, Cu, Zn, Ag) were incorporated in gas diffusion electrodes and used in zero-gap electrolyzers to reach varying FEs for CO of <1% (Fe,Ni), 11% (Cu), 37% (Zn), 75% (Co) and nearly 100% (Ag) at a current density of 50 mA cm-2.encatalysiscopperReduktionKyoto protocolElektrolysejournal article
