A research team from Tokyo University of Science, Tohoku University, and Mitsubishi Materials has developed a groundbreaking photocatalytic technology that splits water using sunlight to generate hydrogen gas. The new method involves selectively loading ultrafine rhodium-chromium mixed oxide (Rh₂‒xCrₓO₃) cocatalysts on specific crystal facets of the strontium titanate (STO) photocatalyst, resulting in 2.6 times higher photocatalytic activity compared to traditional methods. This development is a significant step toward creating a sustainable energy society, with further improvements anticipated as it is combined with other advanced photocatalysts.
