In a new two-step strategy, ruthenium dioxide (RuO2) nanocrystals are synthesized and exploited as counter-electrode catalysts. The mechanism of electrocatalysis for triiodide reduction is investigated systematically by first-principles calculations. The electrochemical triiodide reduction reaction on RuO2 catalyst surfaces can be enhanced significantly, owing to the ideal combination of good electrocatalytic activity and high electrical conductivity.
