Summary:
- This article discusses the development of a new catalyst made from iridium that can efficiently produce hydrogen gas from water. Hydrogen is a clean-burning fuel that could be used to power vehicles and generate electricity.
- The catalyst is able to split water molecules into hydrogen and oxygen using sunlight, which is an important step towards creating a sustainable source of hydrogen fuel.
- The researchers have created a "megalibrary" of over 100,000 different iridium-based catalysts to find the most effective one for this process, demonstrating the power of high-throughput screening to accelerate materials discovery.
