Highly efficient and stable indium single-atom catalysts for electrocatalytic reduction of CO2 to formate

Abstract

Indium single-atom catalysts display a large total current density (38.94 to 81.08 mA cm⁻²) over an extensive potential window (−0.91 to −1.41 V vs. RHE) for electrocatalytic CO₂ reduction to formate with high selectivity (85.2% faradaic efficiency at −1.31 V).
