An expeditious synthesis of early transition metal carbide nanoparticles on graphitic carbons

An expeditious synthesis of metal carbide nanoparticles onto various carbon supports is demonstrated. The procedure is versatile and readily yields TiC, VC, Mo2C and W2C nanoparticles on different types of carbons. The reaction is initiated at room temperature and proceeds within seconds.

This novel synthetic route paves the way to a large variety of metal carbide-carbon nanocomposites that may be implemented in emerging nanotechnology fields.

The Active State of Supported Ruthenium Oxide Nanoparticles during Carbon Dioxide Methanation

CO2 methanation is an old process but it is one of the keys to produce chemicals of interest. One of the research trend is to go to lower reaction temperatures, which promote highly selective reactions (i.e. formation of methane without carbon monoxyde by-products). Ruthenium nanoparticles are active at low temperature in this process.

Near-Ambient-Pressure X-Ray Photoelectron Spectroscopy (NAP-XPS) was used to monitoring ruthenium nanoparticles deposited on a tailored TiO2 surface. We showed that the ruthenium is metallic under model reaction conditions and we also were able to analyze the nature of the adsorbates as a function of the temperature.

[Article] Observer la surface d’une nanoparticule pendant l’acte catalytique

La surface d’un métal est susceptible de profondes reconstructions lorsqu’on l’expose à des gaz. Ceci reste vrai dans le cas de nanoparticules métalliques ne contenant que quelques milliers d’atomes. Parmi les outils disponibles pour suivre ces transformations fugaces, la spectroscopie de photoélectrons X sous pression de gaz s’est fortement développée ces dernières années.

Electron Microscopy for the Chemists of Materials

Electron microscopy is a central tool in materials sciences and nanochemistry. Combining tomography with electron energy loss spectroscopy and high-magnification imaging in high-angle annular dark-field mode provides access to all features of the same object.

In this feature article, we teamed up with colleagues from Strasbourg, CEA Le Ripault, Toulouse and Paris to illustrate a few contributions of electron microscopy techniques in the field of nanomaterials: silica fibers, porous metal oxides, MOFs and metal phosphide nanoparticles.
