Fate of L-DOPA in the Presence of Inorganic Matrices: Vectorization or Composite Material Formation?

Maguy Jaber, Meryem Bouchoucha, L. Delmotte, Christophe Méthivier, Jean-Marc Krafft, Jean-François Lambert

Novel bionanocomposite materials were successfully prepared using 2:1 phyllosilicates and an amino acid, L-DOPA. A systematic study of DOPA interactions with these smectites and with a nonporous amorphous silica (Aerosil) used for comparison was undertaken by combining macroscopic information,…

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…

Photocatalytic Hydrogen Evolution Using Ni–Pd/TiO 2 : Correlation of Light Absorption, Charge-Carrier Dynamics, and Quantum Efficiency

Ana Luna, Diana Dragoe, Kunlei Wang, Patricia Beaunier, Ewa Kowalska, Bunsho Ohtani, Daniel Bahena Uribe, Miguel A. Valenzuela, Hynd Remita, Christophe Colbeau-Justin

TiO2 surface modification with bimetallic nano particles (NPs) has demonstrated to be a strategy to enhance the hydrogen generation via photocatalysis and to minimize the use of expensive noble metals. A better understanding of the role of bimetallic NPs is of crucial importance to design efficient…

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…

Influence of pretreatment and reaction conditions on the catalytic activity of HAlBEA and CoHAlBEA zeolites in vinyl chloride formation from 1,2-dichloroethane

Izabela Kamińska, Dmytro Lisovytskiy, Laetitia Valentin, Christophe Calers, Yannick Millot, Emil Kowalewski, Anna Śrębowata, Stanislaw Dzwigaj

HAlBEA and CoHAlBEA zeolite catalysts treated at 523 K or 873 K for 3 h in Ar, H2/Ar or air flows, respectively, were investigated in catalytic dehydrochlorination of 1,2-dichloroethane (DCE). The dehydrochlorination of DCE on these zeolite catalysts resulted in almost 100% selectivity to vinyl…
