Identification and Distribution of Surface Ions in Low Coordination of CaO Powders with Photoluminescence Spectroscopy

Hugo Petitjean, Jean-Marc Krafft, Michel Che, Helene Lauron-Pernot, Guylene Costentin

Oxide ions in low coordination (O-LC(2-)) Play a major role in adsorption and catalysis properties of CaO powders. They also give specific photoluminescence features that could be used to characterize the distribution of these ions at the molecular level, but up to now, the photoluminescence of…

Effect of postsynthesis preparation procedure on the state of copper in CuBEA zeolites and its catalytic properties in SCR of NO with NH3

Rafal Baran, Frederic Averseng, Dominik Wierzbicki, Karolina Chalupka, Jean-Marc Krafft, Teresa Grzybek, Stanislaw Dzwigaj

Copper-containing BEA zeolites, Cu2.0SiBEA and Cu2.0HAlBEA, with 2 wt % of Cu were prepared by a two-step postsynthesis method and a conventional wet impregnation, respectively. These zeolites were characterized by XRD, DR UV–vis, EPR, FTIR and TPR physicochemical techniques. The incorporation of…

Surface-generated copper ions induce multilayer growth of small peptides

Jessem Landoulsi, Vincent Dupres, Christophe Méthivier, Ivan Leteyi Mfiban, Pauline Cornette, Elodie Colaço, Claire-Marie Pradier

Herein, we investigate the adsorption behavior of a small peptide, Glu-Cys-Gly, in aqueous solution onto copper surface and unravel a mechanism of growth of a hybrid peptide-copper multilayer the thickness of which may exceed a hundred of nanometers. Thanks to a combined set of surface…

In situ detection and characterization of potable water biofilms on materials by microscopic, spectroscopic and electrochemistry methods

Jean Gamby, Alain Pailleret, Carol Boucher Clodic, Claire-Marie Pradier, Bernard Tribollet

We studied biofilm formation on stainless steel occurring in a drinking water distribution system which operated in parallel at 20 and 37 °C, in order to focus on the effect of temperature rather than on other operational and water quality parameters. A surface conditioning step was followed as a…

Enhancement of water remediation by innovative photocatalytic luminous textiles reactor: Performance, kinetic modeling, and mechanistic insights

Sarra Karoui, Aymen Amine Assadi, Achraf Ghorbal, Lotfi Khezami, Achraf Assadi, Sivachandiran Loganathan, Abdeltif Amrane

To address wastewater treatment, a photocatalytic process using luminous-textile has been proposed due to its high efficiency and non-toxicity. In the present work, the photodegradation of Ciprofloxacin (CIP) in the liquid phase was studied in a compact reactor with a luminous-textile catalyst in…

Impact of Mn addition on catalytic performance of Cu/SiBEA materials in total oxidation of aromatic volatile organic compounds

Anna Rokicińska, Patrycja Majerska, Marek Drozdek, Sebastian Jarczewski, Laetitia Valentin, Jianhong Chen, Adam Slabon, Stanislaw Dzwigaj, Piotr Kuśtrowski

Dealuminated BEA zeolite (SiBEA) was chosen as a support of metal oxide(s) phase for catalytic combustion of volatile organic compounds (VOCs). Copper and/or manganese oxide(s) were deposited at various Cu/Mn molar ratios. Factors influencing the catalytic activity were found by chosen…

Non-destructive investigation of fibronectin adsorption on titanium surfaces using PM-RAIRS: effect of surface hydroxylation

Stéphanie Boudesocque, Olivier Dargaud, Lorenzo Stievano, Christophe Méthivier, Jean-Francois Lambert, T. Coradin, Claire-Marie Pradier

Polarisation-modulation reflection-absorption infrared spectroscopy (PM-RAIRS) is a useful non-destructive technique to study semi-quantitatively the adsorption of proteins on metal surfaces. In this work, we employed PM-RAIRS to study the effect of the degree of hydroxylation of the surface of…
