Size-induced structural modifications affecting Co3O4 nanoparticles patterned in SBA-15 silicas

Anne Davidson, Irene Lopez, Nissrine El Hassan, Hadjira Guerba, Gilles Wallez

The structure of Co3O4 nanoparticles patterned in SBA-15 silicas is studied. With pore size of 7.3 nm, bundles of oriented particles, with (400) plane parallel to the hexagonal axis, is revealed by HR-TEM. With decreasing pore sizes, structural modifications, suggested by HR-TEM are confirmed by…

Reshaping Dynamics of Gold Nanoparticles under H2 and O2 at Atmospheric Pressure

Adrian Chmielewski, Jun Meng, Beien Zhu, Yi Gao, Hazar Guesmi, Hélène Prunier, Damien Alloyeau, Guillaume Wang, Catherine Louis, Laurent Delannoy, Pavel Afanasiev, Christian Ricolleau, Jaysen Nelayah

Despite intensive research efforts, the nature of the active sites for O2 and H2 adsorption/dissociation by supported gold nanoparticles (NPs) is still an unresolved issue in heterogeneous catalysis. This stems from the absence of a clear picture of the structural evolution of Au NPs at near…

Factors impacting the aggregation/agglomeration and photocatalytic activity of highly crystalline spheroid- and rod-shaped TiO 2 nanoparticles in aqueous solutions

Thomas Degabriel, Elodie Colaço, Rute F Domingos, Karim El Kirat, Dalil Brouri, Sandra Casale, Jessem Landoulsi, Jolanda Spadavecchia

We investigate the characteristics, fate and photocatalytic activity of spheroid- and rod-shaped TiO2 nano-crystals in aqueous solutions to better understand their behaviour in media of biological and environmental interest. For this purpose, the potential of a solvothermal method in synthesizing…

Surface-dependent sulfidation and orientation of MoS 2 slabs on alumina-supported model HDS catalysts

Cédric Bara, Anne-Félicie Lamic-Humblot, Emiliano Fonda, Anne-Sophie Gay, Anne-Lise Taleb, Elodie D Devers, Mathieu D Digne, Gerhard D Pirngruber, Xavier Carrier

The constant improvement of hydrotreating (HDT) catalysts, driven by industrial and environmental needs, requires a better understanding of the interactions between the oxide support (mostly alumina) and the MoS2 active phase. Hence, this work addresses the support-dependent genesis of MoS2 on four…

Factors affecting the long-term stability of mesoporous nickel-based catalysts in combined steam and dry reforming of methane

K. Jabbour, N. El Hassan, A. Davidson, S. Casale, Pascale Massiani

An ordered mesoporous " one-pot " nickel-alumina catalyst (5 wt% Ni) was synthesized using the evaporation-induced self-assembly method. Compared to an impregnated and to a non-porous catalysts, the ordered "one-pot" Ni-alumina sample displayed, after in-situ reduction, the…

Bridging Hydroxyls on Anatase TiO$_2$ (101) by Water Dissociation in Oxygen Vacancies

Immad M Nadeem, George T Harrison, Axel Wilson, Chi L Pang, Jörg Zegenhagen, Geoff Thornton

Titanium dioxide is a promising candidate for photocatalytic H$_2$ fuel production, and understanding water splitting on TiO$_2$ surfaces is vital toward explaining and improving the generation of H$_2$. In this work, we electron irradiate anatase TiO$_2$ (101) at room temperature to create…
