摘要：The electrocatalytic reduction of CO_(2) presents a promising strategy in addressing environmental and energy crisis.Significant progress has been achieved via CO_(2) gas diffusion electrolysis,to react at high selectivity and high rate.However,the gas diffusion layer(GDL)of the gas diffusion electrode(GDE)still suffers from low tolerance and limited active sites.Here,the hydrophobic 1-octadecanethiol molecular was functionalized over the Cu catalyst layer of the GDE,which simultaneously stabilizes the GDL and exposes abundant active solid-liquid-gas three-phase interfaces.The resultant GDE exhibits multi-carbon(C_(2+))product selectivity over faradaic efficiency(FE)of 70.0%in the range of 100 to 800 mA·cm^(-2),with the peak FE^(c2+)of 85.2%at 800 mA·cm^(-2).Notably,the strengthened GDE could continuously drive high-current electrolysis for more than 100 h without flooding.This work opens a new way to improve CO_(2) gas diffusion electrolysis via surface molecular engineering.
