Encapsulation of Ru nanoparticles: Modifying the reactivity toward CO and CO2 methanation on highly active Ru/TiO2 catalysts

Aiming at a better understanding of the complex interactions between metal nanoparticles (NPs) and oxide supports, ranging from purely electronic metal-support interactions (EMSIs) to structural modifications associated with strong metal-support interactions (SMSIs), we investigated the impact of a temperature programmed reduction treatment (TPR) of a highly active Ru/TiO2 catalyst on its physical properties and its CO and CO2 methanation...
