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…

Bimetallic Au-Ag/TiO2 catalyst prepared by deposition-precipitation: High activity and stability in CO oxidation

A. Sandoval, A. Aguilar, C. Louis, Agnes Traverse, Rodolfo Zanella

Au-Ag bimetallic catalysts supported on TiO2 were prepared by sequential deposition-precipitation method, silver first and then gold. Au-Ag catalysts with different Au/Ag atomic ratios were synthesized. XANES and H2 TPR results show that gold is more easily reduced in bimetallic catalysts than in…

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…

Successive Strong Electrostatic Adsorptions of [RhCl6]3– on Tungstated-Ceria as an Original Approach to Preserve Rh Clusters From Sintering Under High-Temperature Reduction

Jeffrey Miller, Neil Schweitzer, Mimoun Aouine, Philippe Vernoux, Abdelmalik Boufar, Juliette Blanchard, Jean-Marc Krafft, Christophe Méthivier, Céline Sayag, Frédéric Ser, Mickaël Sicard, Cyril Thomas

Supported transition metal materials have been identified as ideal candidates for decades to catalyze various reactions of interest in the fields of hydrocarbon refining, energy and environmental catalysis. As the resources in transition metals on earth are known to be limited, it appears to be of…

Influence of the ultrasound power density in the ultrasound-assisted synthesis of Ni-based LDH catalysts for CO2 methanation

Michel Obeid, Christophe Poupin, Madona Labaki, Sharad Gupta, Samer Aouad, François Delattre, Ferdaous Ben Romdhane, François Devred, Eric Gaigneaux, Josefine Schnee, Edmond Abi-Aad

Ultrasound-assisted co-precipitation method was used to synthesize Ni-LDH based catalysts for CO2 methanation. The influence of ultrasonic irradiation power density (90, 180, 270, and 360 W·L−1) on the physico-chemical properties of the catalysts as well as on their catalytic behavior was studied…

Insights into bacteriophage T5 structure from analysis of its morphogenesis genes and protein components.

Yvan Zivanovic, Fabrice Confalonieri, Luc Ponchon, Rudi Lurz, Mohamed Chami, Ali Flayhan, Madalena Renouard, Alexis Huet, Paulette Decottignies, Alan R Davidson, Cécile Breyton, Pascale Boulanger

Bacteriophage T5 represents a large family of lytic Siphoviridae infecting Gram-negative bacteria. The low-resolution structure of T5 showed the T=13 geometry of the capsid and the unusual trimeric organization of the tail tube, and the assembly pathway of the capsid was established. Although major…
