Effect of Choline Proline Ionic Liquid Additives on Hydrogen Evolution in Alkaline Water Electrolysis.

Conventional hydrogen generation mostly depends on steam methane reforming (SMR), thereby contributing to greenhouse gas emissions. Alkaline water electrolysis using KOH is a promising method for green hydrogen production, but faces significant technical challenges such as high energy consumption and lower hydrogen production. Despite extensive research on various electrolyte modifications, a significant gap exists in the application of biodegradable and biocompatible amino acid-based ionic liquids as electrolyte additives.
