摘要

The electrochemical conversion of CO2 into liquid fuels is a promising strategy for achieving carbon neutrality. Tin dioxide (SnO2) shows a notable ability to electrocatalytically convert CO2 into formate, though its efficiency is significantly limited by its low catalytic activity. Herein, we construct facet-oriented SnO2 nanoflowers all standing on a three-dimensional nickel hollow fiber that exhibits superior CO2-to-formate electrocatalytic performance. A formate selectivity of 94% and stability of 300 h with a current density of 1.3 A cm−2 at −1.1 V (vs. reversible hydrogen electrode [RHE]) are attained under ambient conditions. Notably, an extremely high CO2 single-pass conversion rate of 85% is achieved, outperforming prominent catalysts reported in electrocatalysis. The synergetic combination of the unique nanostructures and their advanced spatial configuration is proposed to be responsible for the facet-oriented SnO2 with a hierarchical structure, providing fully exposed active sites and facilitating mass and charge transfers. Enhanced mass transfer in the hollow fiber electrode verified by electrochemical measurements and well-retained Sn4+ species confirmed by in situ spectroscopy synergistically boost the high CO2 conversion activity. In situ spectroscopy and theoretical calculation results demonstrate that the SnO2(101) facet favors ∗OCHO intermediate formation and ∗HCOOH desorption, leading to high formate selectivity. This study provides a straightforward approach to the precise fabrication of composite hollow fiber electrodes, enabling highly efficient electrocatalytic reactions with gas molecules. © 2025 The Authors
