Effect of the niobium state on the properties of NbSiBEA as bifunctional catalysts for gas- and liquid-phase tandem processes

Pavlo I. Kyriienko, Olga V. Larina, Nataliia O. Popovych, Sergiy O. Soloviev, Yannick Millot, Stanislaw Dzwigaj

NbSiBEA zeolites contained isolated framework mononuclear Nb(V) (Nb0.7SiBEA) and a mixture of framework mononuclear and extra-framework polynuclear Nb(V) (Nb2.0SiBEA) were prepared by two-step postsynthesis method as evidenced by XRD, NMR, DR UV–vis and FTIR. DR UV–vis showed that two types of…

Unveiling the M−F/OH bonding and anionic ordering in Mg, Zn, Cu−based hydroxyfluorides for the design of basic catalysts

Helies Boumali, Matthew R. Suchomel, Étienne Durand, Thomas Onfroy, Guillaume Laugel, Hélène Pernot

Functional inorganic materials, mostly oxides but also fluorides, sulfides, or nitrides has led to the development of many modern technologies. The usual way to improve the chemical and physical properties of these materials was the cationic substitution in order to tune the chemical bonding. These…

Effects of dealumination on the performance of Ni-containing BEA catalysts in bioethanol steam reforming

Wojciech Gac, Magdalena Greluk, Grzegorz Słowik, Yannick Millot, Laetitia Valentin, Stanislaw Dzwigaj

The effects of dealumination of BEA zeolite on the formation of nickel active sites and the performance of Ni-containing BEA zeolite catalysts in the steam reforming of ethanol have been studied. Ni-containing BEA zeolite catalysts were prepared by the impregnation of unmodified and dealuminated…

How does CO capture process on microporous NaY zeolites? A FTIR and DFT combined study

Olivier Cairon, Hazar Guesmi

Reliable experimental IR and theoretical approaches, both investigating CO adsorption on NaY faujasites, are supporting that CO capture occurs through the completion of the vacant coordination of Na+ cations located in the accessible SII sites. As a result, carbonyl adsorbed species are formed by…
