This study explores the substrate diffusion electrode (SDE) and its performance under varying process parameters. Key factors such as separation layer material, electrolyte, catalyst properties, and stoichiometry are investigated for their impact on electrochemical hydrogenation efficiency. The results emphasize the importance of local water and substrate concentration in optimizing faradaic efficiency, offering insights for improving SDE-based reactions.
