Bulk TiO2 vs alternative Ti-based photocatalysts for the mild aerobic oxidation of alcohols, Masse de TiO2 versus photocatalyseurs alternatifs à base de titane de l’oxydation ménagée et aérobie d’alcools

Diaa Obaid

A series of metal oxides semiconductors, including commercially available TiO2 or synthesized mesoporous samples, were tested as photocatalysts for the aerobic mild oxidation of alcohols in acetonitrile under UV. Benzyl alcohol, used as a reference, was oxidized mainly into benzaldehyde. Best yield…, Des oxydes semi-conducteurs, en particulier TiO2 commercialement disponible ou des échantillons mésoporeux synthétisés, ont été testés comme photocatalyseurs de l'oxydation ménagée et aérobie d'alcools dans l'acétonitrile sous UV. L'alcool benzylique a été oxydé principalement…

On the chemistry of the conversion coatings

Oumaïma Gharbi, Kevin Ogle, Junsoo Han

A conversion coating is an inorganic or organic–inorganic hybrid surface film conveying specific desirable functions to a material, formed by a spontaneous reaction between the material and an electrolyte. This chapter reviews the fundamental physical chemistry of the conversion coating process and…

Biocidal Properties of a Glycosylated Surface: Sophorolipids on Au(111)

Claire Valotteau, Christophe Calers, Sandra Casale, Jan Berton, Christian V. Stevens, Florence Babonneau, Claire-Marie Pradier, Vincent Humblot, Niki Baccile

Classical antibacterial surfaces usually involve antiadhesive and/or biocidal strategies. Glycosylated surfaces are usually used to prevent biofilm formation via antiadhesive mechanisms. We report here the first example of a glycosylated surface with biocidal properties created by the covalent…

Covalent shaping of polyoxometalate molecular films onto ITO electrodes for charge trapping induced resistive switching

Raphaël Salles, Wei Church Poh, Maxime Laurans, Florence Volatron, Antoine Miche, Sandra Alves, Christian Carino, Ludovic Tortech, Guillaume Izzet, Pooi See Lee, Anna PROUST

As nano-sized molecular oxides, polyoxometalates (POMs) hold great promise in non-volatile memory materials based on redox-active molecules. Materials processed from solution, by drop-casting, by embedding POMs in polymers, or using Layer-by-Layer deposition techniques have thus been reported and…

Porous nickel-alumina derived from metal-organic framework (MIL-53): a new approach to achieve active and stable catalysts in methane dry reforming

Leila Karam, Julien Reboul, Sandra Casale, Pascale Massiani, Nissrine El Hassan

An Al‐containing MIL‐53 metal‐organic framework with very high surface area (SBET=1130 m2.g−1, N2 sorption) was used as sacrificial template to prepare a nickel‐alumina‐based catalyst (Ni0AlMIL) highly active and stable in the reaction of dry reforming of methane (DRM). The procedure consisted in…

HRTEM and STEM-HAADF characterisation of Au-TiO2 and Au-Al2O3 catalysts for a better understanding of the parameters influencing their properties in CO oxidation

L. Delannoy, R.L. Chantry, S. Casale, Z.Y. Li, Yves Borensztein, C. Louis

Gold catalysts supported on titania (Au-TiO2) and alumina (Au-Al2O3) were prepared by deposition- precipitation with urea and then activated before characterisation and reaction in CO oxidation, either by calcination in air at 500 1C or reduction under H2 at 300 1C. Gold nanoparticles with average…
