Effect of Cs impregnation on the properties of platinum in Pt/Na-BEA and Pt/Cs-BEA catalysts

Pascale Massiani, E.R. Silva, F.R. Ribeiro, M.F. Ribeiro, J.M. Silva

The presence of alkali cations in zeolite framework provides peculiar basic properties that influence the characteristics and reactivity of supported metal particles. Particularly, the addition of increasing amounts of cesium in Pt/Na-BEA and Pt/Cs-BEA catalysts, by CsOH impregnation, leads to…

Bi2O3, BiVO4, and Bi2WO6: Impact of Surface Properties on Photocatalytic Activity under Visible Light

Tamar Saison, Nicolas Chemin, Corinne Chaneac, Olivier Durupthy, Valerie Ruaux, Laurence Mariey, Françoise Mauge, Patricia Beaunier, Jean-Pierre Jolivet

Bismuth-based oxides have attractive photocatalytic properties under visible light. A better understanding of the origin of that good photocatalytic activity should allow its control and its optimization. In this Article, we have studied the impact of surface properties on photocatalytic activity…

Catalytic Pyrolysis of Plastics over Maghemite-Impregnated Mesocellular Foam using Induction Heating

Luing Wong Syie, Sabino Armenise, B. Nyakuma Bemgba, Soon Ng Pang, Hau Lee Chia, Anna Bogush, Franck Launay, Evgeny Rebrov, Marta Munoz

Pyrolysis is a key technology that converts unrecyclable end-of-life plastics into value-added products. Nevertheless, the high energy consumption during plastic pyrolysis limits the economic feasibility of a scaled-up process. Development of an energy-efficient plastic pyrolysis process is…

Ni-Silica-based Catalysts for CH4 Reforming by CO2 with Enhanced Stability: Recent Designs and the Impacts of Ni Confinement, Promoters, and Core-Shell Structures

Oscar Daoura, Maya Boutros, Franck Launay

CO2 reforming of CH4, also referred to as the Dry Reforming of Methane (DRM), is considered an excellent method to produce H2 and CO (syngas), which are known to be used for the production of higher alkanes and oxygenates. Despite nickel’s moderate toxicity, Ni-based heterogeneous catalysts are…

Elaboration, activity and stability of silica-based nitroaromatic sensors

D. Mercier, Franck Pereira, Christophe Méthivier, Pierre Montméat, Lionel Hairault, Claire-Marie Pradier

Functionalized silica-based thin films, modified with hydrophobic groups, were synthesized and used as sensors for nitroaromatic compound (NAC) specific detection. Their performance and behavior, in terms of stability, ageing and regeneration, have been fully characterized by combining chemical…

Bimetallic Au-Ag/TiO2 catalyst prepared by deposition-precipitation: High activity and stability in CO oxidation

A. Sandoval, A. Aguilar, C. Louis, Agnes Traverse, Rodolfo Zanella

Au-Ag bimetallic catalysts supported on TiO2 were prepared by sequential deposition-precipitation method, silver first and then gold. Au-Ag catalysts with different Au/Ag atomic ratios were synthesized. XANES and H2 TPR results show that gold is more easily reduced in bimetallic catalysts than in…
