Tuesday publication update! 📖 In this newest publication from #NorthwesternUniversity and the #TUDenmark, authors Yukun Liua, Kunmo Kooa, Zugang Maoa, Xianbiao Fud, Xiaobing Hua and Vinayak P. Dravid looked at Pd catalysts using the #AtmosphereAX System!
Palladium (Pd) catalysts play a crucial role in the direct synthesis of H₂O via hydrogen oxidation, a reaction with both practical and fundamental significance. While this process has been widely studied, the mechanisms and kinetics of intermediate reaction stages remain elusive due to the complex interplay of adsorption, atomic diffusion, and phase transformations.
Using gas-cell transmission electron microscopy (TEM), they captured the real-time dynamics of Pd-catalyzed water formation, revealing:
🔬 Reversible Pd hydride formation directly linked to water generation.
🔥 Reaction rate sensitivity to the gas introduction sequence.
📊 Electron diffraction & DFT calculations confirming that precursor adsorption limits the reaction rate.
These nanoscale insights optimize reaction conditions for Pd-catalyzed hydrogen oxidation and can inspire further investigation into fundamental reaction mechanisms.
