 This study focused on the development of gold nanocatalysts with varying tail groups attached to them. The tail groups were designed to affect the performance of the catalyst in terms of efficiency, selectivity, and durability. It was found that the tail groups had a significant impact on the catalyst's ability to reduce oxygen, as well as its stability over time. This research demonstrates how the chemical properties of the ligand can have a major impact on the interaction between the catalyst and the electrolyte and reactants.
