Direct Synthesis of H2O2 from H2 and O2 over Gold, Palladium, and Gold-Palladium Catalysts Supported on Acid-Pretreated TiO2

Direct Synthesis of H2O2 from H2 and O2 over Gold, Palladium, and Gold-Palladium Catalysts Supported on Acid-Pretreated TiO2

Palladium‐ringed gold: The acid‐pretreated Au–Pd catalysts supported on TiO2 have a well‐defined gold‐rich core (blue) and palladium‐rich shell (green). This type of core and shell enhances the catalytic activity of the catalyst for the direct synthesis of H2O2 from H2 and O2.
