Room-Temperature Synthesis of Iron-Doped Anatase TiO2 for Lithium-Ion Batteries and Photocatalysis

Christian Andriamiadamanana, C. Laberty-Robert, Moulay Tahar Sougrati, Sandra Casale, Carine Davoisne, Snehangshu Patra, Frédéric Sauvage

Iron-doped nanocrystalline particles of anatase TiO2 have been successfully synthesized using a complete room-temperature synthetic approach, leading to particles of high surface area (280 m2/g) and a narrowed band gap of 2.3 eV. These particles were introduced for photocatalysis under white light…

Mesocellular silica foam-based Ni catalysts for dry reforming of CH4 (by CO2)

Oscar Daoura, Marie-Nour Kaydouh, Nissrine El-Hassan, Pascale Massiani, Franck Launay, Maya Boutros

Nickel-containing mesocellular silica foam (MCF) catalysts were prepared for dry reforming of methane (DRM). Different methods were used for the synthesis of the MCFs supports in order to enhance their surface areas and pore volumes. The incorporation of nickel was done by three different methods:…

Context. The nearby and young M star AU Mic is surrounded by a debris disk in which we previously identified a series of large-scale arch-like structures that have never been seen before in any other debris disk and that move outward at high velocities.Aims. We initiated a monitoring program with…
