Superior Stability of Au/SiO 2 Compared to Au/TiO 2 Catalysts for the Selective Hydrogenation of Butadiene

Nazila Masoud, Laurent Delannoy, Herrick Schaink, Ad van Der Eerden, Jan Willem de Rijk, Tiago A. G. Silva, Dipanjan Banerjee, Johannes D. Meeldijk, Krijn P. de Jong, Catherine Louis, Petra E. de Jongh

Supported gold nanoparticles are highly selective catalysts for a range of both liquid-phase and gas-phase hydrogenation reactions. However, little is known about their stability during gas-phase catalysis and the influence of the support thereon. We report on the activity, selectivity, and…

Calibrated Co3O4 nanoparticles patterned in SBA-15 3 silicas: Accessibility and activity for CO oxidation

Irène Lopes, Anne Davidson, Cyril Thomas

The catalytic performances in CO oxidation of Co3 O4 nanoparticles patterned in the porosity of SBA-15 silicas are investigated. 10 Accessibility limitations of the reactants to the catalytic sites are clearly revealed,when the Co3O4 nanoparticles are embedded in the 11 SBA-15 pores.Despite these…

Corrosion and protection of high leaded tin bronze covered with patina in NaHCO3 + Na2SO4 solution simulating acid rain in urban environment

Kamal Rahmouni, Suzanne Joiret, Luc Robbiola, A. Srhiri, Hisasi Takenouti, Vincent Vivier

An experimental procedure for obtaining reproducible patina on high leaded tin bronze, B66 (Cu-8Sn-14Pb in wt %) has been devised, followed by its isolation from the substrate and examination of the electrochemical behaviour in a solution of 0.2 g.L - 1 Na 2 SO 4 + 0.2 g.L - 1 NaHCO 3 acidified to…

Investigating the DMPO-formate spin trapping method for the study of paper iron gall ink corrosion

Alice Gimat, Valeryia Kasneryk, Anne-Laurence Dupont, Sabrina Paris, Frederic Averseng, Jeanine Fournier, Pascale Massiani, Véronique Rouchon

Paper degradation by iron gall ink is a challenging issue for the conservation of ancient manuscripts. It is usually attributed to both FeII catalyzed oxidation and acid catalyzed hydrolysis of cellulose, yet the dominant degradation pathway remains an open question. In this work, electron spin…

Investigation of ionic surfactant-selective electrodes by EIS

Claude Gabrielli, Patrick Hemery, Pierre Letellier, Michele Masure, Hubert Perrot, Marie-Isabelle Rahmi, Mireille Turmine

A model of ionic surfactant-selective electrodes with mobile ionic sites is proposed. The steady-state concentrations of the active species are calculated. The electrochemical impedance of the membrane immersed between electrolytic solutions is given. This model is in good agreement with the…

Study of gold electrodissolution by scanning electrochemical microscopy in different modes

Divino Salvador Ramírez-Rico, Michel Keddam, Erika Roxana Larios-Durán, Vincent Vivier

The electrodissolution of gold has already been widely studied by several methods, but no consensus concerning the reaction mechanism has been reached. In this work, the scanning electrochemical microscopy (SECM) has been used in transient condition for studying the electrodissolution of gold in…

Improved Experimental Setup to Reach a Broad Frequency Domain in Local Electrochemical Impedance Spectroscopy Measurements

Maurilio Pereira Gomes, Samantha Michelle Gateman, Isolda Costa, Oumaïma Gharbi, Kieu Ngo, Jesualdo Luiz Rossi, Mireille Turmine, Vincent Vivier

We report a new experimental setup enabling local electrochemical impedance spectroscopy (LEIS) measurements over a wide frequency range, including the low frequency domain. First, an improved signal treatment was performed using a potential shifter to minimize the DC component of the measured…

Palladium Nanowires Synthesized in Hexagonal Mesophases: Application in Ethanol Electrooxidation

Faygal Ksar, Geetarani Surendran, Laurence Ramos, Bineta Keita, Louis Nadjo, Eric Prouzet, Patricia Beaunier, Agnes Hagege, Fabrice Audonnet, Hynd Remita

Palladium nanowires (of length a few tens of nanometers) are synthesized in a hexagonal mesophase formed by a quaternary system (Pd-doped water, surfactant, cosurfactant, and oil) by electron beam irradiation. The mesophases can be doped by high concentrations of palladium (0.1 M) without any…
