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. The clusters, measuring less than 1 nanometer, show high catalytic activity for hydrogen evolution reactions.
The method involves a one-pot synthesis using a common iridium precursor and a mild reducing agent, avoiding complex steps or harsh conditions. This approach allows for precise control over cluster size, which is critical for optimizing catalytic performance.
According to the team, the nanoclusters demonstrate superior activity compared to conventional iridium catalysts, potentially reducing the amount of precious metal needed in applications like water splitting for hydrogen production. The findings were published in a peer-reviewed journal.
The researchers emphasize that the simplicity of the method could enable large-scale production, making it more accessible for industrial use. Further studies are planned to explore the clusters' performance in other catalytic reactions.
