Rh-Ni/SBA-15 prepared by two solvents method as stable catalysts for the dry reforming of methane at high pressure

M.N. Kaydouh, El Hassan N., Elzakhem H., Anne Davidson, Sandra Casale, Pascale Massiani

The effect of Rh addition on the catalytic performance of Ni/SBA-15 catalysts was studied in the dry reforming of methane. The SBA-15 silica support was synthesized in large quantities and the metals were deposited using the two solvents impregnation method. The properties of the calcined, reduced…

Beneficial effect of gelatin on iron gall ink corrosion

Alice Gimat, Anne Michelin, Pascale Massiani, Véronique Rouchon

Iron gall Inks corrosion causes paper degradation (browning, embrittlement) and treatments were developed to tackle this issue. They often include resizing with gelatin to reinforce the paper and its cellulosic fibers (of diameter approx. 10 µm). This work aimed at measuring the distribution of ink…

Optimization and Antibacterial Response of N-Halamine Coatings Based on Polydopamine

Nadia Nazi, Adeline Marguier, Catherine Debiemme-Chouvy, Vincent Humblot

RessouDue to the ability of microorganisms to first adhere to a material surface and then to lead to the formation of a biofilm, it is essential to develop surfaces that have antimicrobial properties. It is well known that N-halamine coatings allow us to prevent or minimize such phenomena. In the…

The genesis of a heterogeneous catalyst: in situ observation of a transition metal complex adsorbing onto an oxide surface in solution

Antoine Hervier, Juliette Blanchard, Guylène Costentin, John R. Regalbuto, Catherine Louis, Souhir Boujday

Understanding the interactions between metal complexes and oxide surfaces is crucial to the synthesis of supported metal catalysts. Recently developed in situ techniques have made it possible to closely characterize the solid/liquid interface. For the first time, the adsorption of platinum…

Preparation of two series of VxSiBeta zeolite catalysts with V centres in framework and extra-framework positions and their application in selective oxidation of methanol

Maciej Trejda, Yannick Millot, Karolina Chalupka, Stanislaw Dzwigaj

Two series of V-containing Beta zeolites have been prepared by contacting of the aqueous NH 4 VO 3 solution with two SiBeta zeolites at pH = 2.5 and 6, respectively. Because of the presence in NH 4 VO 3 solution at pH = 2.5 mainly monomeric VO 2 + ions, vanadium have been easily incorporated into…

EIS investigation of zinc dissolution in aerated sulfate medium. Part I: bulk zinc

Chantal Cachet, F. Ganne, Georges Maurin, J. Petitjean, Vincent Vivier, Robert Wiart

The kinetics of anodic dissolution and corrosion of zinc are investigated by electrochemical impedance spectroscopy in sulfate medium for various surface preparation conditions and different experimental procedures. A new version of the reaction model, which was established previously, accounts…

Tuning the Growth Mode of 3D Silver Nanocrystal Superlattices by Triphenylphosphine

Karima Ouhenia-Ouadahi, Amandine Andrieux-Ledier, Johannes Richardi, Pierre-Antoine Albouy, Patricia Beaunier, Peter Sutter, Eli Sutter, Alexa Courty

Here, we show that the residual presence of reaction products markedly influences the growth mode of 3D superlattices made of silver nanocrystals. The silver nanocrystals (5 or 6 nm in diameter) are synthesized via the reduction of a silver triphenylphosphine complex in the presence of thiols. The…
