Experimental techniques reveal hydroxide and hydrogen interactions in electrochemical systems, indicating adsorption effects.
Key Points
The study identifies four voltammetric peak features at Pt(100) electrodes, highlighting the role of hydrogen and hydroxide adsorbates.
Experimental findings show that below peak I, hydrogen is the main adsorbate, while a mixed adsorption region appears between peaks II and III.
First-principles calculations reveal two potential values of maximum entropy, indicating heightened disorder that enhances charge transfer at the interface.
Results suggest a need for optimizing electrode-electrolyte interfaces in Pt-based nanostructured materials for better energy conversion.
