Abstract
Cu acetate/PAN nanofibers were transformed into porous C nanofibers with doped N and Cu particles,<italic>via</italic>O<sub>2</sub>partial pressure-controlled calcination. N atoms next to Cu trigger the CO<sub>2</sub>RR by increasing the amount of CO* on the Cu, lowering the energy needed for CO dimerization.
