Oxidation of gold metal particles supported on TiO2: an FTIR study by means of low-temperature CO adsorption

Hr. Klimev, Katia Fajerwerg, K. Chakarova, L. Delannoy, C. Louis, K. Hadjiivanov

Two Au/TiO2 samples with different gold loadings (0.7 and 4.0 wt.% Au) were prepared by deposition-precipitation with urea and calcined at 673 K. TEM revealed gold particles of 3.2 and 3.9 nm for the 0.7 and 4.0 wt.% samples, respectively. The samples were subjected to different red-ox treatments…

Evidence of Pd segregation and stabilization at edges of AuPd nano-clusters in the presence of CO: A combined DFT and DRIFTS study

Beien Zhu, Gode Thrimurthulu, Laurent Delannoy, Catherine Louis, Christine Mottet, Jerome Creuze, Bernard Legrand, Hazar Guesmi

Combined Density Functional Theory (DFT) calculations and Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) were performed to study the distribution of Pd atoms in bimetallic AuPd nanoparticles in the presence of adsorbed CO. Compared to vacuum condition, the results showed…

Metal–Support Interactions in Pt-WO 3 Heterostructures: Role of WO 3 Polymorphism

Isabel Gómez-Recio, Cyril Thomas, Christophe Méthivier, María Luisa Ruiz-González, José González-Calbet, David Portehault

Ionic exchange under soft conditions yields nanoplatelets of tungsten bronzes with an original crystal structure doped with cobalt, copper, platinum, and cesium cations (h′-MxWO3). The optimal orientation of the tunnel-based crystal structure, perpendicular to the basal plane of the nanoplatelets,…

Nanoscale heterostructures of covalent intermetallics should give birth to a wide range of interface-driven physical and chemical properties. Such a level of design however remains unattainable for most of these compounds, due to the difficulty to reach a crystalline order of covalent bonds at the…
