Settling a decades-long debate, new research conclusively shows that a hierarchy of active species exists in gold on iron oxide catalysis designed for low temperature carbon monoxide oxidation; Nanoparticles, sub-nanometer clusters and dispersed atoms—as well as how the material is prepared—are all important for determining catalytic activity.
Scientists have created promising gold-indium oxide nanoparticles through room-temperature oxidation.
Researchers from the University of Houston and Trinity University have for the first time provided direct evidence of a water-mediated reaction mechanism for the catalytic oxidation of carbon monoxide. read more
A new study details for the first time a new type of catalytic site where oxidation catalysis occurs, shedding new light on the inner workings of the process.
Researchers believe that the puzzle of catalytic gold is now partially solved. Gold can catalyze an oxidation reaction by first oxidizing itself. New research evidence on gold-oxide phase at room temperature and atmospheric pressure...
