    Catalytic combustion of methane has been studied for many years due to its applications in power generation and emissions clean-up. Among different catalysts, Pd-based materials are the most active for the catalytic ...
  • 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
    Restricted access - publisher's policy
    CuO 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 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
    Restricted access - publisher's policy
    The 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 ...
