Incorporation of vanadium into the framework of hydroxyapatites: importance of the vanadium content and pH conditions during the precipitation step

Sarah Petit, Thrimurthulu Gode, Cyril Thomas, Stanislaw Dzwigaj, Yannick Millot, Dalil Brouri, Jean-Marc Krafft, Gwenaelle Rousse, Christel Laberty-Robert, Guylène Costentin

Even though vanadium-modified hydroxyapatite (V-HAp) samples are very promising systems for oxidative dehydrogenation of propane, the incorporation of vanadium into the hydroxyapatite framework was reported to be limited and to lead to over-stoichiometric compounds. Here, the synthesis of a Ca10(…

Application of computational approach in plastic pyrolysis kinetic modelling: a review

Sabino Armenise, Syieluing Wong, José M Ramírez-Velásquez, Franck Launay, Daniel Wuebben, Bemgba B Nyakuma, Joaquín Rams, Marta Muñoz

During the past decade, pyrolysis routes have been identified as one of the most promising solutions for plastic waste management. However, the industrial adoption of such technologies has been limited and several unresolved blind spots hamper the commercial application of pyrolysis. Despite many…

Evidence for an H2 promoting effect in the selective catalytic reduction of NO(x) by propene on Au/Al2O3.

Tesnim Chaieb, Laurent Delannoy, Sandra Casale, Catherine Louis, Cyril Thomas

This work provides the first experimental evidence of an H2 effect in C3H6-SCR over an Au/Al2O3 catalyst. This effect could only be observed when the number of Au catalytic sites was decreased. The N2 turnover rate estimated for the first time for the Au catalytic sites for H2–C3H6-SCR was found to…

Incorporation of Mn into the vacant T-atom sites of a BEA zeolite as isolated, mononuclear Mn: FTIR, XPS, EPR and DR UV-Vis studies

R. Baran, L. Valentin, Stanislaw Dzwigaj

A MnSiBEA zeolite has been prepared via a two-step postsynthesis procedure which consisted, in the first step, of the treatment of a tetraethylammonium BEA zeolite with nitric acid for the formation of vacant T-atom sites and then, in the second step, of the incorporation of Mn ions into the…

A New Nanocomposite: L-DOPA/Laponite

Maguy Jaber, Jean-Francois Lambert

A simple procedure is reported to obtain original nanocomposite materials combining the smectite Laponite and melanin-like polymers. Aq. polymn. of L-DOPA is considerably accelerated in the presence of suspended Laponite particles, and its mechanism is significantly modified with respect to…

In situ surface imaging: High temperature environmental SEM study of the surface changes during heat treatment of an Al Si coated boron steel

M. Barreau, C. Méthivier, T. Sturel, C. Allely, P. Drillet, S. Cremel, R. Grigorieva, B. Nabi, Renaud Podor, J. Lautru, V. Humblot, J. Landoulsi, X. Carrier

Al-Si coated boron steels have been of interest for many years because of their superior mechanical properties and their excellent oxidation resistance. These high strength steels are particularly used in hot stamping processes during which the Al-Si coating undergoes multiple microstructural…
