Abstract

An efficient electrocatalyst was fabricated by thermally treating Bi₂S₃ nanorods in H₂ followed by O₂, demonstrating much superior performance compared to pristine Bi₂S₃ and that treated just in H₂ for CO₂ electroreduction to formate with 39.5 mA cm⁻² partial current density at −1.0V_RHE and 97.7% maximum faradaic efficiency in an H-cell.
