F and B co-modification activated Cu/NC catalyst for enhanced electrocatalytic CO2 reduction to CH4†

Abstract

A fluorine and boron co-modified Cu/NC catalyst with adjustable electronic structure was obtained for robust electrocatalytic CO₂-to-CH₄, the obtained F, B–Cu/NC catalyst exhibited 57% faradaic efficiency for CH₄ production at −1.377 V vs. RHE, surpassing that of unmodified or single-modified catalysts.
