Vibrating single probe and stationary bi-probes to measure local electrochemical impedance spectroscopy.

Hisasi Takenouti, G. Galicia, Michel Keddam, Vincent Vivier

The electrochemical impedance spectroscopy is widely used to investigate the electrode kinetics. This method is recognized as a powerful method to discriminate one reaction model to another and also to evaluate the reaction rate of elementary steps. However, when the electrode kinetics is markedly…

Discrimination of infrared fingerprints of bulk and surface POH and OH of hydroxyapatites

Sarah Diallo-Garcia, Manel Ben Osman, Jean-Marc Krafft, Souhir Boujday, Guylene Costentin

The identification of the nature of the surface acid base pairs present on hydroxyapatites surface is a key point to rationalize their catalytic properties. To investigate the possible involvement of acidic protonated phosphate (POH) and/or of basic OH emerging from the channels, the spectroscopic…

Controlled Formation of Native Defects in Ultrapure ZnO for the Assignment of Green Emissions to Oxygen Vacancies

Fredeŕic Averseng, Miao Zhang, Frederic Averseng, Jean-Marc Krafft, Patrizia Borghetti, Guylène Costentin, Slavica Stankic

Ultrapure ZnO nanopowders were synthesized via vapor-phase based methods under oxygen deficient conditions. The type and relative proportions of intrinsic point defects were studied by photoluminescence (PL) and EPR spectroscopies performed under strictly controlled conditions. Besides coupled PL/…

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…

In situ observation of atomic redistribution in alloying gold-silver nanorods

Jessi E S van Der Hoeven, Tom a J Welling, Tiago a G da Silva, Jeroen E van den Reijen, Camille La Fontaine, Xavier Carrier, Catherine Louis, Alfons van Blaaderen, Petra E de Jongh

The catalytic performance and optical properties of bimetallic nanoparticles critically depend on the atomic distribution of the two metals in the nanoparticles. However, at elevated temperatures, during light induced heating or during catalysis atomic redistribution can occur. Measuring such metal…

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…

Versatile and robust synthesis process for the fine control of the chemical composition and core-crystallinity of spherical core-shell Au@Ag nanoparticles

Suyeon Lee, Hervé Portalès, Michael Walls, Patricia Beaunier, Nicolas Goubet, Benoit Tremblay, Jérémie Margueritat, Lucien Saviot, Alexa Courty

Au nanoparticles (NPs) characterized by distinct surface chemistry (including dodecanethiol or oleylamine as capping agent), different sizes (~5 and ~10 nm) and crystallinities (polycrystalline or single crystalline), were chosen as seeds to demonstrate the versatility and robustness of our two-…
