Abstract: High Resolution Image Download MS PowerPoint Slide Electrochemical CO 2 reduction reaction (CO 2 RR) has emerged as a key negative-emission technology, yet its industrial adoption hinges on cathode catalysts that deliver high selectivity and production rates at low cost. Herein, we reported a facile hydrothermal route to synthesize different scales of ZnOHF ultrathin nanowires with hybridized ZnO/ZnOHF heterointerfaces, where the 40 nm variant (NW 40 -ZnOHF) showed a high FE of 93 % and a j CO of −17.2 mA/cm 2 at −1.0 V vs RHE. The excellent intrinsic electrocatalytic properties of NW 40 -ZnOHF were verified, presumably owing to its high-level surface concentration of oxygen vacancies preexisted in the pristine structure and formed during CO 2 RR. This work highlights the significance of the synergistic effect of heterointerface and fluorine incorporation engineering for guiding the optimized design of low-cost electrocatalysts for CO 2 RR technology.
