6 The configuration of Cu-S 1 N 3 /Cu x was clearly confirmed by X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) analysis. Copper cut like homeobox 1 Homo sapiens
7 The as-prepared Cu-S 1 N 3 /Cu x composite presents a 100% Faradaic efficiency towards CO generation (FE CO ) at -0.65 V vs. RHE and high FE CO over 90% from -0.55 to -0.75 V, outperforming the analogue with a Cu-N 4 coordination sphere (FE CO only 54% at -0.7 V). Iron cut like homeobox 1 Homo sapiens
