Platinum surface modification with cerium species and the effect against the methanol anodic reaction
(Elsevier B.V. Sa, 2008-06-15)
Spontaneous deposition and electrochemical deposition by potential perturbation programs were used to place cerium-containing species on platinum surfaces in acid solution. Cyclic voltammetric profiles of cerium-modified ...
Degradation of dipyrone via advanced oxidation processes using a cerium nanostructured electrocatalyst material
This work studied the degradation of dipyrone, via electrochemical processes and via electro-Fenton reaction using a 4% CeO2/C gas diffusion electrode (GDE) prepared via modified polymeric precursor method. This material ...

Amorphous silicates containing cerium: selective catalysts for the oxidation of cyclohexane
(Elsevier Science BvAmsterdamHolanda, 2001)
Novel catalytic ceramic papers applied to oxidative dehydrogenation of ethane
The aim of this work was the development of novel structured catalysts applied to the oxidative dehydrogenation of ethane. Different Ni-based catalytic formulations promoted with cerium were incorporated onto ceramic papers ...
Efficient structured catalysts for ethylene production through the ODE reaction: Ni and Ni–Ce on ceramic foams
Ni and Ni-Ce oxides alumina-supported formulations onto alpha-alumina foams were prepared, characterized and evaluated in the oxidative dehydrogenation of ethane (ODE) reaction. The catalysts were appropriately deposited ...
Influence of the preparation method and the support on H2O 2electrogeneration using cerium oxide nanoparticles
This work describes the influence of the preparation method and the carbon support using a low contentof cerium oxide nanoparticles (CeO2/C 4%) on H2O2electrogeneration via the oxygen reduction reac-tion (ORR). For this ...
