CuO and CeO2 catalysts supported on Al2O3, ZrO2, and SiO2 in the oxidation of CO at low temperature Aguila, Gonzalo; Gracia, Francisco; Araya Figueroa, Paulo (ELSEVIER, 2008-07-01)The effect of the support, Al2O3, ZrO2, and SiO2, on the activity for CO oxidation of a series of CuO and CeO2 monometallic and bimetallic catalysts was studied. The catalysts were prepared by coimpregnation of the support ...

Navas-Cárdenas, Carlos; Benito, Noelia; Wolf, Eduardo E.; Gracia, Francisco (Elsevier B.V., 2019)In this work, the catalytic properties of Pt/MOx/TiO2 (M = Fe, Co) catalysts prepared by strong electrostatic adsorption (SEA), were investigated for the preferential oxidation (PROX) of CO in H2. The SEA method was chosen ...

Jiménez, Romel; Fuentes, Karla; Medina, María Paz; Godoy, Sebastián; Gracia, Francisco; Karelovic, Alejandro (Elsevier Ltd, 2019)© 2018 Hydrogen Energy Publications LLC The effect of H 2 O pressure (P H2O ) on CH 4 formation turnover rate (TOF CH4 ) was evaluated as a function of Rh cluster size. In-situ DRIFTS and kinetic measurements were used to ...
