Abstract
En 中文
Electrochemical CO2 reduction (ECR) in aprotic electrolytes holds significant potential for mitigating CO2 emissions while producing valuable chemicals. However; challenges such as the hydrogen evolution reaction and electrolyte crossover; caused by the hydrophilicity of the anion exchange membrane (AEM) used in the ECR system; greatly hinder its efficiency. This study introduces a facile hydrophobic modification strategy employing hydrophobic polytetrafluoroethylene (PTFE) as a cover layer for the AEM. This approach markedly enhances the ECR performance in the dimethyl sulfoxide (DMSO) catholyte.
