Local Reaction Environment Deviations within Gas Diffusion Electrode Pores for CO₂ Electrolysis

The local conditions inside a gas diffusion electrode (GDE) pore, especially in the electrical double layer (EDL) region, influence the charge transfer reactions and the selectivity of desired CO₂ER products. Most GDE computational models ignore the EDL or are limited in their applicability at high potentials. In this work, we...

Electrochemical Reduction for Metal Recovery in Water Treatment: A Novel Approach
