Carbon Hollow Fiber Penetration Electrode with Unsaturated Ni-N₂ Coordination for Enhanced CO₂ Electroreduction.

ABSTRACT: Hollow fiber gas penetration electrodes with a compact hierarchical pore structure have emerged as promising platforms for CO₂ electroreduction. However, developing carbon hollow fiber electrodes with efficient CO₂ electrocatalytic performance remains unexplored and challenging. Herein, a straightforward strategy is presented to fabricate robust, self-standing carbon hollow fiber electrodes modified with an unsaturated Ni-N₂ coordination structure. This unique hollow fiber electrode configuration effectively enhances the kinetics of CO₂ electro-conversion to CO. Both density functional theory (DFT) calculations and experimental studies reveal that the Ni-N₂ structure significantly boosts electrocatalytic activity for CO₂ red
