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…

On the preparation of multifunctional conversion coatings of FePO 4 /LiFePO 4

S. Valverde-Pérez, R. Figueroa, X.R. Nóvoa, D.S. Ramírez-Rico, Vincent Vivier

This research aims to take advantage of the properRes of phosphate coaRngs to overcome the problems inherent in using LiFePO4 as a powder. LiFePO4 coaRngs have been prepared on iron sheets using cyclic voltammetry in an aqueous soluRon of H3PO4 and LiOH. The voltammograms evolved from the iniRal…

In situ observation of atomic redistribution in alloying gold-silver nanorods

Jessi E S van Der Hoeven, Tom a J Welling, Tiago a G da Silva, Jeroen E van den Reijen, Camille La Fontaine, Xavier Carrier, Catherine Louis, Alfons van Blaaderen, Petra E de Jongh

The catalytic performance and optical properties of bimetallic nanoparticles critically depend on the atomic distribution of the two metals in the nanoparticles. However, at elevated temperatures, during light induced heating or during catalysis atomic redistribution can occur. Measuring such metal…
