Characterization and catalytic activity of Mn (salen) immobilized on silica by various strategies

Khalil Tesnime Abou, Chaaben Semy Ben, Boujday Souhir, Bergaoui Latifa

Different strategies were applied to prepare supported Mn(salen) on fumed silica and to explore the effect of the interaction nature between the active sites and the surface on the catalytic activity. Direct and multistep grafting methods were used: the silica surface was silylated and the metal…

Adsorption of dyes from aqueous solution under batch mode using cellulosic orange peel waste

Sami Guiza, Launay Franck, Mohamed Bagané

The present work aimed at studying the use of orange peel (OP) biosorption for the removal of methylene blue (MB) and Congo red (CR) from aqueous solution. The influences of initial dye concentration and contact time on the biosorption process were studied. Experimental data were modeled by…

Black Phosphorus-Based Compound with Few Layers for Photocatalytic Water Oxidation

Junqing Yan, Yujin Ji, Lingqiao Kong, Youyong Li, Miriam Navlani-García, Shengzhong Frank Liu, Yasutaka Kuwahara, Kohsuke Mori, Michel Che, Hiromi Yamashita

Although black phosphorus (BP) is an interesting 2D nanosheet material with a high hole mobility, its application in the photocatalytic water oxidation for O2 evolution is not reported yet. Herein the use of BP coupled with a reductive hydroxide, Ni(OH)2, is reported for the first time. The…

Chemical Preparation of Supported Bimetallic Catalysts. Gold-Based Bimetallic, a Case Study

Catherine Louis

This review focuses on the chemical methods used to prepare supported bimetallic heterogeneous catalysts, i.e., bimetallic nanoparticles deposited on a support. The review is limited to the preparation of gold-based bimetallic catalysts and moreover to bimetallic nanoparticles supported on powder…

Influence of organic additives on the properties of impregnationsolutions and on nickel oxide particle size for Ni/Al2O3catalysts

Faiza Bentaleb, Michel Che, Anne-Claire Dubreuil, Cécile Thomazeau, Eric Marceau

tThe introduction of organic additives, such as polyols, sugars or polyacids, in impregnation solutionshas been suggested to better control the size of nanoparticles on supported catalysts. The present paperfocuses on the roles played by three of these additives, sorbitol, glucose and citric acid,…

Control of calcium accessibility over hydroxyapatite by post-precipitation steps: influence on the catalytic reactivity toward alcohols

Manel Ben Osman, Sarah Diallo Garcia, Jean-Marc Krafft, Christophe Methivier, Juliette Blanchard, Tetsuya Yoshioka, Jun Kubo, Guylène Costentin

Hydroxyapatites are increasingly used as heterogeneous catalysts since they present atypical behaviours for many acid base reactions. The aim of this study was to discuss the possible involvement of Ca2+ Lewis and/or PO–H Brønsted acid sites belonging to the hydroxyapatite system in the conversion…

Antibacterial properties of sophorolipid-modified gold surfaces against Gram positive and Gram negative pathogens

Claire Valotteau, Ibrahim M. Banat, Christopher A. Mitchell, Helen Lydon, Roger Marchant, Florence Babonneau, Claire-Marie Pradier, Niki Baccile, Vincent Humblot

Sophorolipids are bioderived glycolipids displaying interesting antimicrobial properties. We show that they can be used to develop biocidal monolayers against Listeria ivanovii, a Gram-positive bacterium. The present work points out the dependence between the surface density and the antibacterial…

Synthesis of supported ZSM-5 nanoparticles

Olfa Ben Moussa, Ilef Borghol, David Hu, Sandra Casale, Yannick Millot, Celine Sayag, Juliette Blanchard, Olivier Durupthy

The influence of the support on the nucleation of ZSM-5 nanoparticles has been studied for three supports: γ-alumina, zirconia and carbon nanotubes (CNT). While zeolite nucleation was suppressed in presence of alumina and strongly delayed in presence of zirconia, it occurred without delay in…
