Unusual behaviour of Au/ZnO catalysts in selective hydrogenation of butadiene due to the formation of a AuZn nanoalloy

Salim Derrouiche, Camille La Fontaine, Gode Thrimurtulu, Sandra Casale, Laurent Delannoy, Hélène Lauron-Pernot, Catherine Louis

The reaction of selective hydrogenation of butadiene performed in an excess of propene, which has been extensively studied over gold supported on different oxides and exhibited high selectivity to butenes, has been applied to the case of gold (1 wt%) supported on zinc oxide (8 m2 g−1), a strongly…

Platinum-zeolite hybrid catalyst for the electrooxidation of formic acid

Lu Zhang, Juan V Perales-Rondón, Angélica Thomère, Juliette Blanchard, Carlos M Sánchez-Sánchez

Formic acid oxidation reaction (FAOR) was studied using different platinum-zeolites hybrid catalysts. The catalysts were prepared by addition of two different forms of the ZSM-5 zeolite (ZSM-5-H+ and ZSM-5-NH4+) to an ink containing Vulcan carbon support and Pt nanoparticles (NPs). TEM images…

Measuring Changes in Wettability and Surface Area during Micro Droplet Corrosion Measurements

Samantha Michelle Gateman, Oumaïma Gharbi, Mireille Turmine, Vincent Vivier

We report a new method for directly monitoring dynamic surface wetting that occurs during electrochemical droplet cell corrosion measurements on an Al alloy and Cu galvanic couple. The combination of a goniometer and potentiostat enabled the in situ observation of wettability during polarization of…

Fatty Acid Monolayers on Randomly Nanostructured Inorganic Surfaces: Interplay of Wettability, Chemistry, and Topography

Mathieu Beauvais, Irma Liascukiene, Alain Jonas, Jessem Landoulsi

Understanding the wetting properties of chemically modified inorganic surfaces with random nanoscale topographies is of fundamental importance for diverse applications. This issue has hitherto continuously been the subject of considerable controversies. Herein, we report a thorough investigation of…

Selective Catalytic Reduction of NO x over Au/Al2O3: Influence of the Gold Loading on the Promoting Effect of H2 in H2-Assisted C3H6-SCR of NO x

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

This article reports on the promotional effect of adding H2 to the reaction feed for the selective catalytic reduction of NO x with propene (H2–C3H6-SCR) over Au/Al2O3 catalysts. For this purpose, the influence of the Au loading in H2–C3H6-SCR was investigated. The H2 promoting effect in C3H6-SCR,…
