Tailoring Borate Mediator Species Enables Industrial CO Production with Improved Overall Energy Efficiency by Sustainable Molten Salt CO₂ Electrolysis.

ABSTRACT: The electrochemical conversion of CO₂ into CO represents a promising strategy for mitigating excessive global greenhouse gas emissions. Nevertheless, achieving industrial-scale electrochemical CO₂-to-CO conversion with enhanced selectivity and reduced energy consumption presents significant challenges. In this study, a borate-enhanced molten salt process for CO₂ capture and electrochemical transformation is employed, achieving over 98% selectivity for CO and over 55% energy efficiency without the necessity for complex and costly electrocatalysts. Cathodic CO₂ electro-reduction (CO₂ER) with the anodic oxygen evolution reaction (OER) at an overall current density of 500 mA cm^-2 using non-nanostructured transition-metal plate e
