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…

Toward new proton exchange batteries based on ionic liquid electrolyte: Metal hydride electrode / electrolyte coupling

Nesrine Chaabene, J. Zhang, Mireille Turmine, E. Kurchavova, Vincent Vivier, F. Cuevas, M. Mateos, M. Latroche, J. Monnier

The voltage of an alkaline electrolyte-based battery is limited by the narrow electrochemical stability window of water. As an alternative to water, protic ionic liquid (IL)-based electrolytes have shown excellent conducting properties as well as a wide electrochemical stability window, and can…

Deciphering the Adsorption Mechanisms of RGD Subunits: L-Aspartic Acid on Cu(110)

Roberta Totani, Christophe Méthivier, Hervé Cruguel, Claire-Marie Pradier, Vincent Humblot

In this work we present a detailed surface science characterization of L-Aspartic acid adsorption on a Cu(110) surface. We replaced the traditional sublimation method to obtain molecular films by dosing aspartic acid directly from an aqueous solution through an Electrospray Ionization (ESI) device…

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…

Hydrogen and syngas production by methane dry reforming on SBA-15 supported nickel catalysts: On the effect of promotion by Ce0.75Zr0.25O2 mixed oxide

Abdulkader Albarazi, Patricia Beaunier, Patrick da Costa

In this work, the effects of doping Ni-based SBA-15 catalysts with Ceria-Zirconia mixed oxide (CZ) on the activity and stability of these catalysts during syngas production by methane dry reforming (MDR) were investigated and compared with the activity and stability of unmodified Ni/SBA-15. The…

Enhanced selective nitroarene hydrogenation over Au supported on b-Mo2C and b-Mo2C/Al2O3

Noemie Perret, Xiaodong Wang, Laurent Delannoy, Claude Potvin, Catherine Louis, Mark A. Keane

b-Mo2C and b-Mo2C/Al2O3 have been synthesised via temperature programmed carburisation and employed, for the first time, as supports for gold catalysts. 1%w/w Au/Mo2C and Au/Mo2C/Al2O3 were prepared by deposition-precipitation with urea and used to promote the gas phase hydrogenation of para-…

The synergistic power of theory and experiment in the field of catalysis

Frederik Tielens, Monica Calatayud

Potential energy curves, equilibrium interatomic distances, term energies and harmonic vibration frequencies for the 16 lowest states of neutral carbon monoxide and the six lowest states of singly ionized carbon monoxide are calculated by density functional theory (DFT) and linear-response time-…
