This work aims to enhance the durability and performance of gas diffusion electrodes (GDE) during the electrocatalytic reduction of carbon dioxide.
Constructed a gas diffusion layer using a sacrificial template method and solvothermal induction.
Evaluated catalytic performance of a nanostructured copper catalyst under constant conditions.
Investigated real-time wettability changes on the GDL surface through electrowetting and durability tests.
Achieved stable electroreduction for up to 69 h at 200 mA/cm² current density.
Demonstrated no flooding at -2.0V vs. RHE, indicating superior selectivity and voltage stability compared to commercial GDLs.
Revealed flooding mechanism insights during the catalytic process through wettability tests.
