Catalytic conversion of trichloroethylene on nickel containing beta zeolites into value added products

A. Śrębowata, R. Baran, D. Lisovytskiy, I.I. Kamińska, S. Dzwigaj

Nickel containing BEA zeolites, NiSiBEA and NiHAlBEA, with 2 wt% of Ni were prepared by a two-step postsynthesis method and conventional wet impregnation. The calcination of NiSiBEA and NiHAlBEA at 773 K for 3 h in air led to the formation of C-NiSiBEA and C-NiHAlBEA. After reduction at 873 K for 3…

Gold Nanoparticles Assembly on Silicon and Gold Surfaces: Mechanism, Stability and Efficiency in Diclofenac Biosensing

Maroua Ben Haddada, Maria Hübner, Sandra Casale, Dietmar Knopp, Reinhard Niessner, Michele Salmain, Souhir Boujday

We investigated the assembly of Gold nanoparticles (AuNPs) on Gold and Silicon sensors with two final objectives: (i) understanding the factors governing the interaction and (ii) building up a nanostructured piezoelectric immunosensor for diclofenac, a small-sized pharmaceutical pollutant.…

l-Methionine adsorption on Cu(110), binding and geometry of the amino acid as a function of coverage

Christophe Méthivier, Vincent Humblot, Claire-Marie Pradier

The adsorption of l-methionine on Cu(110) has been characterized by combining in situ Polarization Modulation Infrared Reflection Absorption Spectroscopy (PM-IRRAS) and X-ray Photoelectron Spectroscopy (XPS). Both the chemical state of the molecule, and its anchoring points were determined at…

Fischer carbene mediated covalent grafting of a peptide nucleic acid on gold surfaces and IR optical detection of DNA hybridization with a transition metalcarbonyl label

Pratima Srivastava, Mahsa Ghasemi, Namrata Ray, Amitabha Sarkar, Jana Kocabova, Stepanka Lachmanova, Magdalena Hromadova, Souhir Boujday, Silvia Cauteruccio, Emanuela Licandro, Pramod Thakare, Céline Fosse, Michèle Salmain

Amine-reactive surfaces comprising N-hydroxysuccinimide ester groups as well as much more unusual Fischer alkoxymetallocarbene groups were generated on gold-coated surfaces via self-assembled monolayers of carboxy- and azido-terminated thiolates, respectively. These functions were further used to…

High activity of mononuclear copper present in the framework of CuSiBEA zeolites in the selective catalytic reduction of NO with NH3

Rafal Baran, Teresa Grzybek, Thomas Onfroy, Stanislaw Dzwigaj

CuxSiBEA zeolites (with x = 1–7.5 Cu wt %) prepared by a two-step postsynthesis method which consists in the first step of dealumination of parent BEA zeolite to obtain aluminum-free SiBEA support and then in the second step, of contacting the obtained material with an aqueous solution of copper…

Influence of natural adsorbates of magnesium oxide on its reactivity in basic catalysis

Damien Cornu, Hugo Petitjean, Guylène Costentin, Hazar Guesmi, Jean-Marc Krafft, Hélène Lauron-Pernot

Solid materials possessing basic properties are naturally covered by carbonates and hydroxyl groups. Those natural adsorbates modify their chemical reactivity. This article aims to specifically evidence the role of surface carbonates and hydroxyls in basic heterogeneous catalysis on MgO. It…

Influence of acid–base properties of Mg-based catalysts on transesterification: role of magnesium silicate hydrate formation

Damien Cornu, Longfei Lin, Maya Mounir Daou, Maguy Jaber, Jean-Marc Krafft, Virginie Herledan, Guillaume Laugel, Yannick Millot, Hélène Lauron-Pernot

The transesterification reaction assisted through heterogeneous basic catalysis was thoroughly studied because of its importance in transforming biomass, as for biodiesel production or lactone opening. As catalysts with the strongest basic properties are not always the most efficient ones, a series…

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…
