  • Ambient pressure photoemission spectroscopy reveals the mechanism of carbon soot oxidation in ceria-based catalysts 

    Soler Turu, Lluís; Casanovas Grau, Albert; Escudero, Carlos; Pérez-Dieste, Virginia; Aneggi, Eleonora; Trovarelli, Alessandro; Llorca Piqué, Jordi (2016-06-27)
    Article

    Removing soot is one of the most important challenges in minimizing the impact of combustion engines on the environment. Catalysts based on CeO2 have proved suitable to oxidize soot due to their capacity to store and release ...
  • CO oxidation and COPrOx over preformed Au nanoparticles supported over nanoshaped CeO2 

    Soler Turu, Lluís; Casanovas Grau, Albert; Urrich, Aitor; Angurell Purroy, Inmaculada; Llorca Piqué, Jordi (2016-02-10)
    Article
    Restricted access - publisher's policy
    Au/CeO2 (0.25% wt. Au) catalysts were prepared by anchoring preformed Au nanoparticles over ceria polycrystals, cubes and rods and tested in the oxidation of CO and COPrOx. The use of preformed Au nanoparticles assured a ...
  • Finding a suitable catalyst for on-board ethanol reforming using exhaust heat from an internal combustion engine 

    Casanovas Grau, Albert; Jiménez Divins, Nuria; Rejas García, Albert; Bosch Tous, Ricardo; Llorca Piqué, Jordi (2017-05-11)
    Article

    Ethanol steam reforming with pure ethanol and commercial bioethanol (S/C = 3) was carried out inside the housing of the exhaust gas pipe of a gasoline internal combustion engine (ICE) by using exhaust heat (610–620 °C). ...
  • First tests of the applicability of gamma-ray imaging for background discrimination in time-of-flight neutron capture measurements 

    Perez Magan, D. L.; Caballero Ontanaya, L.; Domingo Pardo, César; Agramunt Ros, Jorge; Albiol, F.; Casanovas Grau, Albert; Gonzalez, A.; Guerrero, C.; Lerendegui Marco, J.; Tarifeño Saldivia, Ariel Esteban (2016-07-01)
    Article
    Open Access
    In this work we explore for the first time the applicability of using gamma-ray imaging in neutron capture measurements to identify and suppress spatially localized background. For this aim, a pinhole gamma camera is ...
  • Gold(I)-complex–titania hybrid photocatalyst for hydrogen production 

    Aguiló Linares, Elisabet; Soler Turu, Lluís; Casanovas Grau, Albert; Moro, Artur J.; Lima, Joao Carlos; Rodríguez Raurell, Laura; Llorca Piqué, Jordi (2017-09-08)
    Article

    The integration of TiO2 with a AuI complex containing a thiocoumarin moiety resulted in a very efficient photocatalyst for the generation of H2. The molecular structure of the complex was preserved under the photoreaction ...
  • Hydrogen photoproduction from ethanol-water mixtures over Au-Cu alloy nanoparticles supported on TiO2 

    Bonmatí Lladó, Eduard; Casanovas Grau, Albert; Angurell Purroy, Inmaculada; Llorca Piqué, Jordi (2015-03-01)
    Article
    Open Access
    Au/TiO2, Au0.75Cu0.25/TiO2, Au0.5Cu0.5/TiO2 and Au0.25Cu0.75/TiO2 photocatalysts prepared from pre-formed Au and Au-Cu alloy nanoparticles of controlled composition and size were loaded over ceramic honeycombs (2 mg cm(-2)) ...
