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 ... -
The formation of nanodomains of Ce6O11 in ceria catalyzed soot combustion
Aneggi, Eleonora; Jiménez Divins, Nuria; de Leitenburg, Carla; Llorca Piqué, Jordi; Trovarelli, Alessandro (2014-04)
Article
Accés restringit per política de l'editorialThe behavior of a series of CeO2 catalysts in soot combustion reaction was investigated by HRTEM and XPS. It is shown that nanodomains of reduced ceria in the form of Ce6O11 develop during reaction under oxygen-containing ... -
The influence of nano-architectured CeOx supports in RhPd/CeO2 for the catalytic ethanol steam reforming reaction
Jiménez Divins, Nuria; Casanovas, A.; Xu, W.; Senanayake, S. D; Wiater, Dawid; Trovarelli, Alessandro; Llorca Piqué, Jordi (2015-09-15)
Article
Accés obertThe ethanol steam reforming (ESR) reaction has been tested over RhPd supported on polycrystalline ceria in comparison to structured supports composed of nanoshaped CeO2 cubes and CeO2 rods tailored toward the production ... -
Water splitting reaction on Ce0.15Zr0.85O2 driven by surface heterogeneity
Pappacena, Alfonsina; Boaro, Marta; Armelao, Lidia; Llorca Piqué, Jordi; Trovarelli, Alessandro (2016)
Article
Accés obertCe0.15Zr0.85O2 was investigated in the two-step water splitting reaction. High-temperature treatment in N-2 induced compositional and structural heterogeneities which contributed to a six-fold increase of H-2 yield after ...
