“Nanocasting”: using SBA-15 silicas as hard templates to obtain monodispersed superparamagnetic gamma-Fe2O3 nanoparticles

Anne Davidson, Emilie Delahaye, Virginie Escax, Nissrine El Hassan, Renata Aquino, Vincent Dupuis, Regine Perzynski, Yuri Raikher

This work describes the use of mesoporous SBA-15 silicas as hard templates, for the size-controlled synthesis of oxides nanoparticles, the pores acting as nanoscale reactors. This fundamental work is mainly aimed at understanding unresolved issues concerning the occurrence and size dependence of…

Modification of TiO2 by bimetallic Au–Cu nanoparticles for wastewater treatment

Zibin Hai, Nadia El Kolli, Daniel Bahena Uribe, Patricia Beaunier, Miguel José-Yacaman, Jackie Vigneron, Arnaud Etcheberry, Sébastien Sorgues, Christophe Colbeau-Justin, Jiafu Chen, Hynd Remita

Au, Cu and bimetallic Au–Cu nanoparticles were synthesized on the surface of commercial TiO2 compounds (P25) by reduction of the metal precursors with tetrakis(hydroxymethyl) phosphonium chloride (THPC) (0.5% in weight). The alloyed structure of Au–Cu NPs was confirmed by HAADF-STEM, EDS, HRTEM and…

Revisiting active sites in heterogeneous catalysis: Their structure and their dynamic behaviour

Jacques C. Vedrine

This short review article aims at revisiting the description of active sites in heterogeneous catalysis on solid surfaces and their role in catalyst activity and selectivity. Special emphasis is brought to: (i) structure of the solid surface; (ii) importance of active site isolation on the surface…

UHV Deposition of the Gly-Pro Dipeptide on Cu(110) by Sublimation or Electrospray Ionization

Christophe Méthivier, Vincent Humblot, Claire-Marie Pradier

While most of the peptide adsorption studies, in vacuum, are achieved by sublimation, we demonstrate here the possible use of electrospray ionization (ESI) to deposit entire peptides, possibly surrounded by solvated ions, on a surface in ultra high vacuum (UHV) conditions. This paper is then…

Vanadium incorporation from aqueous NH4VO3 solution into siliceous Beta zeolite determined by NMR with formation of V-single site zeolite catalysts for application in SCR of NO

Rafal Baran, Yannick Millot, Frederic Averseng, Stanislaw Dzwigaj

The speciation of vanadium in initial aqueous NH4VO3 solutions as a function of pH and concentration, in supernatant and in wet solids were investigated by 51V static and MAS NMR. Two series of VSiBeta zeolite catalysts were prepared by a two-step postsynthesis procedure at pH = 2.5 and 6. 51V…

Influence de l'incorporation du vanadium dans l'hydroxyapatite sur la réaction d'oxydation déshydrogénante du propane, Influence of the incorporation of vanadium in hydroxyapatite on the oxidative dehydrogenation of propane reaction

Sarah Petit

Dans l'objectif de combler le gap entre l'offre et la demande en propène, la réaction d'oxydation déshydrogénante du propane (ODHP) est une solution alternative à la réaction de déshydrogénation directe. Les hydroxyapatites (HAp) modifiées au vanadium sont des matériaux bi-…, In order to fill the gap between propene supply and demand, the oxidative dehydrogenation of propane (ODHP) is an alternative solution to the direct dehydrogenation process. Vanadium-modified hydroxyapatites (HAp) are bifunctional catalysts combining acid-base and redox properties which were shown…

Carbon nanowalls functionalization for efficient O2 reduction catalyzed by laccase using design of experiment

Achraf Blout, Jérôme Pulpytel, Shinsuke Mori, Farzaneh Arefi-Khonsari, Christophe Méthivier, Alain Pailleret, Claude Jolivalt

An enzymatic biofuel cell cathode was elaborated by nano-structuration and functionalization of graphite using two consecutive plasma treatments before immobilization of laccase as a biocatalyst to perform oxygen reduction reaction (ORR) by direct electron transfer ((DET). Nano-structuration of…

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…
