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 ...
Effect of cerium (IV) ions on the anticorrosion properties of siloxane-poly(methyl methacrylate) based film applied on tin coated steel
(Pergamon-Elsevier B.V. Ltd, 2010-07-15)
This work investigates the influence of the addition of cerium (IV) ions on the anticorrosion properties of organic-inorganic hybrid coatings applied to passivated tin coated steel. In order to evaluate the specific effect ...
Formation of a cerium conversion coating on magnesium alloy using ascorbic acid as additive: Characterisation and anticorrosive properties of the formed films
Cerium-based conversion coatings were formed on AZ91D magnesium alloy by immersion of the substrate in solutions containing Ce(NO3)3, H2O2 and ascorbic acid (HAsc). The characterisation of the films was performed by ...
Cerium metal- mediated Reformatsky-type reaction with ethyl bromosuccinate for the synthesis of novel paraconic acid analogs
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
The treatment of cerium metal with ethyl bromosuccinate (1) forms the stabilized organolanthanoid intermediate (2), which reacts with carbonyl compounds in a Reformatsky-type reaction, under mild conditions, to produce ...
Influence of cerium (IV) ions on the mechanism of organosilane polymerization and on the improvement of its barrier properties
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
In this work, the effect of cerium (IV) ammonium nitrate (CAN) addition on the polymerization of bis-[triethoxysilyl]ethane (BTSE) film applied on carbon steel was studied. The electrochemical characterization of the films ...
