Abstract

image

Using a new two-step strategy, ruthenium dioxide (RuO2) nanocrystals are successfully synthesized and exploited as counter electrode catalysts, which exhibit promising electrocatalytic activity towards triiodide reduction. By virtue of firstprinciple calculations, the catalytic mechanism of electrocatalysis for triiodide reduction is systematically investigated by H. F. Wang, H. G. Yang, and co-workers on page 484. It is found that the electrochemical triiodide reduction reaction on RuO2 catalyst surfaces can be significantly enhanced, owing to the ideal combination of good electrocatalytic activity and high electrical conductivity.
