The dynamics of PdO-Pd phase transformation in the presence of water over Si-doped Pd/CeO 2 methane oxidation catalysts
Toso, Alessandra; Colussi, Sara; Llorca Piqué, Jordi; Trovarelli, Alessandro (2019-03-25)
Article
Accés obertOne of the main issues for the catalytic abatement of methane from natural gas fueled vehicles over Pd-based materials is due to the large amount of water vapor in the exhausts, which can severely deactivate the catalyst. ... -
The effect of ceria on the dynamics of CuO-Cu2O redox transformation: CuO-Cu2O hysteresis on ceria
Colussi, Sara; Amoroso, Francesco; Katta, Lakshmi; Llorca Piqué, Jordi; Trovarelli, Alessandro (2014-06-01)
Article
Accés restringit per política de l'editorialCuO supported on ceria and alumina is prepared by incipient wetness impregnation and its redox behavior is investigated by means of XRD, XPS and TPO experiments. CuO on ZrO2 and on ceria-zirconia are also synthesized for ... -
The effect of milling parameters on the mechanochemical synthesis of Pd-CeO2 methane oxidation catalysts
Danielis, Maila; Colussi, Sara; de Leitenburg, Carla; Soler Turu, Lluís; Llorca Piqué, Jordi; Trovarelli, Alessandro (2019-01-01)
Article
Accés obertThe preparation of catalytic materials via mechanochemical routes is a very promising alternative to complex wet chemical syntheses due to its simplicity, versatility and ecological advantages. The mechanical mixing of Pd ...
