Gold Oxides – Catalyst for Oxygen Catalysis

gold oxides are very insoluble thermally stable gold sources, suitable for glass, optic and ceramic applications. They decompose at 350 degrees C, releasing oxygen and reverting to elemental gold.In a new study, scientists from RUB have uncovered that water molecules facilitate the activation of molecular oxygen (O2) in aqueous gold/metal...
