Scientists have discovered a new way that oxygen moves in certain catalysts, which are materials that speed up chemical reactions. Traditionally, it was believed that oxygen only moved across the surface of these catalysts. However, using advanced microscopy, researchers found that in Ru/TiO2 catalysts, oxygen can travel directly from the inside of the TiO2 to the Ru particles through their interface, not just along the surface. This movement causes the TiO2 structure to change slightly, creating pathways for oxygen. This discovery is important because it shows that the design of the metal-support interface in catalysts can significantly impact their effectiveness in reactions. Understanding this process could lead to better catalyst designs for industrial applications.
