Catalytic properties of Al13TM4 complex intermetallics: influence of the transition metal and the surface orientation on butadiene hydrogenation
Autor: Laurent Piccolo, Corentin Chatelier, Marie-Cécile De Weerd, Franck Morfin, Julian Ledieu, Vincent Fournée, Peter Gille, Emilie Gaudry
Publikováno v: Science and Technology of Advanced Materials, Vol 20, Iss 1, Pp 557-567 (2019)
Complex intermetallic compounds such as transition metal (TM) aluminides are promising alternatives to expensive Pd-based catalysts, in particular for the semi-hydrogenation of alkynes or alkadienes. Here, we compare the gas-phase butadiene hydrogena

The intermetallic alloy Al5Co2 structure was studied by X-ray photoelectron diffraction and applying the standard software MSCD that shows a (1 × 1) termination. The reliability factor indicated the best termination belongs to the Al-rich surface la

We have determined the crystal structure and the magnetic state of the CeFe$_9$Si$_4$ intermetallic compound. Our revised structural model (fully ordered tetragonal unit cell, I4/mcm) agrees with the previous literature report, except for some minor

Inorganic Chemistry, American Chemical Society, 2019, 59 (1), pp.360-366. ⟨10.1021/acs.inorgchem.9b02545⟩
A new ternary phase with a composition Al1+xV2Sn2–x (x = 0.19) has been found during investigation of the Al–V–Sn ternary system. Single-crystal X-ray diffraction measurements reveal that this ternary phase crystallizes with an orthorhombic str

Acta Crystallographica. Section A, Foundations and Advances
The physical significance of clusters in Al13TM4 compounds is invesitgated through ab initio methods based on density functional theory.
Clusters, i.e. polyhedral geometric entities, are widely used to describe the structure of complex intermeta
