Synergistic effect of bimetallic Au-Pd supported on ceria-zirconia mixed oxide catalysts for selective oxidation of glycerol
(Elsevier Science, 2016-11)
A series of bimetallic Au-Pd catalysts supported on Ce0.62Zr0.38O2mixed oxide has been synthesized usinga simultaneous deposition-precipitation method. Different Au:Pd ratios were obtained maintaining Auloadings constant ...
Gold nanoparticles supported in zirconia-ceria mesoporous thin films: A highly active reusable heterogeneous nanocatalyst
(American Chemical Society, 2015-01)
Gold nanoparticles (NP) trapped in the mesopores of mixed zirconia-ceria thin films are prepared in a straightforward and reproducible way. The films exhibit enhanced stability and excellent catalytic activity in nitro-group ...
Temperature-Scanning Method for the kinetic studies of CO oxidation over ceria-zirconia supported gold catalysts
(ELSEVIER SCIENCE SA, 2015-12-15)
The experimental data of CO oxidation over the series of 2 wt.% Au/Ce1-xZrxO2 (x=0, 0.25, 0.5, 0.75, 1) catalyst were analyzed using a variation of the Temperature Scanning Method with the aim of catalyst's composition ...
Influence of pretreatment atmospheres on the performance of bimetallic Au-Pd supported on ceria-zirconia mixed oxide catalysts for benzyl alcohol oxidation
(Elsevier Science, 2016-09)
Monometallic Au, Pd and bimetallic Au-Pd catalysts supported on a Ce0.62Zr0.38O2mixed oxide have been synthesized by the sol-immobilization method. The catalysts have been characterized by inductively coupled plasma-atomic ...

Diesel/biodiesel soot oxidation with ceo2 and ceo2-zro2-modified cordierites: a facile way of accounting for their catalytic ability in fuel combustion processes
(Sociedade Brasileira de Química, 2011)
CeO2 and mixed CeO2-ZrO2 nanopowders were synthesized and efficiently deposited onto cordierite substrates, with the evaluation of their morphologic and structural properties through XRD, SEM, and FTIR. The modified ...
Study of the water-gas shift reaction over Pt supported on CeO2–ZrO2 mixed oxides
(Elsevier Science, 2011-08)
The water gas shift (WGS) reaction was studied on Pt/CeO2, Pt/ZrO2 and Pt/CexZrx-1O2 catalysts. All the samples were characterized by a variety of physical and spectroscopic techniques. The catalysts activities were evaluated ...
