Silk Bionanocomposites for Organic Dye Absorption and Degradation

Cristina Belda Marín, Christophe Egles, Jessem Landoulsi, Erwann Guénin

Organic dyes are extensively used in the textile, paper and paint industries, among others. However, the lack of efficient treatment of disposals leads to the release of these toxic molecules into the environment, which has an enormous impact on living organisms. Dye absorption is the most common…

How does CO capture process on microporous NaY zeolites? A FTIR and DFT combined study

Olivier Cairon, Hazar Guesmi

Reliable experimental IR and theoretical approaches, both investigating CO adsorption on NaY faujasites, are supporting that CO capture occurs through the completion of the vacant coordination of Na+ cations located in the accessible SII sites. As a result, carbonyl adsorbed species are formed by…

Selectivity in the gas-phase hydrogenation of 4-nitrobenzaldehyde over supported Au catalysts

Noémie Perret, Xiaodong Wang, Thomas Onfroy, Christophe Calers, Mark A Keane

The effects of Au particle size and support properties have been examined in the gas-phase hydrogenation of 4-nitrobenzaldehyde over Au/ZrO2, Au/TiO2 and Au/Al2O3. Gold particle size was varied using deposition-precipitation and impregnation syntheses. The catalysts have been characterised in terms…

In-situ monitoring of transition metal complex adsorption on oxide surfaces during the first stages of supported metal catalyst preparation

Juliette Blanchard, Antoine Hervier, Guylène Costentin, John Regalbuto, Catherine Louis, Souhir Boujday

In the preparation of supported catalysts by deposition, in solution, of a transition metal complex (TMC) on an oxide support, the interactions occurring at the solid/liquid interface between the TMC and the oxide have a crucial impact on the properties of the final catalyst. However, these…

In situ photo-electrochemical investigation using surface X-ray diffraction: from ultra-high vacuum to solid/electrolyte interfaces

Axel Wilson, I M Nadeem, H Hussain, X Torrelles, J Imran, D Garai, Robert Lindsay, Gregory Cabailh, J Zegenhagen, G Thornton, C Nicklin

<div><p>A Photo-ElectroChemical DrOplet Cell (PEC-DOC) has been developed for the I07 surface diffraction beamline of Diamond Light Source to investigate solid-liquid interfaces using Surface X-Ray Diffraction (SXRD). PEC-DOC is ultrahigh vacuum (UHV) compatible, and so can be directly…

Effect of the niobium state on the properties of NbSiBEA as bifunctional catalysts for gas- and liquid-phase tandem processes

Pavlo I. Kyriienko, Olga V. Larina, Nataliia O. Popovych, Sergiy O. Soloviev, Yannick Millot, Stanislaw Dzwigaj

NbSiBEA zeolites contained isolated framework mononuclear Nb(V) (Nb0.7SiBEA) and a mixture of framework mononuclear and extra-framework polynuclear Nb(V) (Nb2.0SiBEA) were prepared by two-step postsynthesis method as evidenced by XRD, NMR, DR UV–vis and FTIR. DR UV–vis showed that two types of…

Investigation of the collapse of bubbles after the impact of a piston on a liquid free surface

Maya Mounir Daou, Elena Igualada, Hugo Dutilleul, Jean-Marie Citerne, Javier Rodríguez-Rodríguez, Stéphane Zaleski, Daniel Fuster

A novel technique based on the impact of a piston on a liquid confined in a vessel is described. Pressure measurements reveal that strong pressure variations (up to 100 atmospheres) with a rich content of frequencies are efficiently transmitted to the liquid. High-speed camera visualizations show…
