Summary

An international research team from Tohoku University, Tokyo University of Science, Vanderbilt University and the University of Adelaide has discovered a novel, exceptionally simple method to precisely synthesize extremely small iridium nanoclusters in ambient air. Such a feat was previously considered highly challenging. In addition, the nanoclusters outperform conventional, commercially available iridium catalysts by 1.5 times in mass activity, while maintaining sustained operational stability without degradation for more than 20 hours. This breakthrough could result in improved production of green hydrogen, which is considered the ultimate clean fuel.
