Hydrothermal Zn–Fe Mixed Oxide Nanocatalysts: Influence of Synthesis Conditions on Physicochemical Properties, Acidity, and Catalytic Activity in the Biginelli Reaction

Samira Slyemi, Juliette Blanchard, Ouzna Kheffache, Hassiba Messaoudi, Sandra Casale, Saremble Guira, Ibtissem Lounas, Meriem Boudjeloud

CeNiO 3 catalyst and its modification with manganese were investigated for dry Reforming of methane reaction. The experiments were performed at 700 °C to examine the effect of manganese loading on catalyst activity and stability. A series of ternary perovskite-type oxides CeNi 1-x Mn x O 3 (x = 0,…

Effects of organic and inorganic treatment agents on the formation of conversion layer on hot-dip galvanized steel: An X-ray photoelectron spectroscopy study

S. Le Manchet, D. Verchere, Jessem Landoulsi

The formation of a Cr-free conversion layer on hot-dip galvanized (HDG) steel involves various interfacial processes which radically influence the composition of the coating and thus its performance. Here, we investigate the role of the main constituents contained in the treatment bath, the…

Transition-Metal-Free Catalysts for the Sustainable Epoxidation of Alkenes: From Discovery to Optimisation by Means of High Throughput Experimentation

Warunee Lueangchaichaweng, Inge Geukens, Annelies Peeters, Benjamin Jarry, Franck Launay, Jean-Luc Bonardet, Pierre A. Jacobs, Paolo P. Pescarmona

Abstract: Transition-metal-free oxides were studied as heterogeneous catalysts for the sustainable epoxidation of alkenes with aqueous H2O2 by means of high throughput experimentation (HTE) techniques. A full-factorial HTE approach was applied in the various stages of the development of 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-…

Inelastic light scattering by long narrow gold nanocrystals: when size, shape, crystallinity and assembly matter

Hervé Portalès, Nicolas Goubet, Sandra Casale, Xiang Zhen Xu, Mostapha Ariane, Alain Mermet, Jeremie Margueritat, Lucien Saviot

We report the synthesis of long narrow gold nanocrystals and the study of their vibrational dynamics using inelastic light scattering measurements. Rich experimental spectra are obtained for monodomain gold nanorods and pentagonal twinned bipyramids. Their assignment involves diameter-dependent non…

Au/xCeO(2)/Al2O3 catalysts for VOC elimination: oxidation of 2-propanol

P. Lakshmanan, L. Delannoy, C. Louis, N. Bion, J.M. Tatibouet

2- Propanol oxidation (1 mol% in air) was investigated over 1% Au/CeO2, 1% Au/Al2O3 and 1% Au/xCeO(2)/Al2O3 (x = 1.5, 3, 5 and 10 wt%) catalysts and the corresponding pure supports. The effects of the catalyst activation procedure (calcination or reduction), cerium oxide morphology and loading, the…
