Chemioselectivity in the catalytic hydrogenation of cinnamaldehyde. Effect of metal particle morphology
TL;DR: The selectivity of platinum and rhodium catalysts for the hydrogenation of cinnamaldehyde into Cinnamyl alcohol is much higher on large, faceted metal particles than on small (<3 nm) particles as discussed by the authors.

Selective Liquid-Phase Hydrogenation of Citral over Supported Palladium
María A. Aramendía,Victoriano Borau,César Jiménez,José M. Marinas,A. Porras,Francisco J. Urbano +5 more
TL;DR: In this article, a low-pressure hydrogenator was used to reduce cathedral in the liquid phase by using catalysts consisting of palladium supported on a mixed 80:20 SiO2/AlPO4 system and sepiolite from Vallecas (Madrid, Spain).

The nature of raney nickel, its adsorbed hydrogen and its catalytic activity for hydrogenation reactions (review)
TL;DR: In this article, the influence of catalyst preparation on the structure, texture and the metallic A1 content is reviewed and two examples of hydrogenation reactions with liquid acetone and gaseous benzene are described and the mechanisms are discussed in relation to the kinetics and the adsorbed hydrogen species.
Journal ArticleDOI
A study of the texture and structure of Raney nickel
TL;DR: The texture of Raney nickel was simultaneously approached by nitrogen adsorption, magnetic measurements, X-ray diffraction line-broadening, Xray small angle scattering and electron microscopy as discussed by the authors.
Journal ArticleDOI
Raney metal catalysts: I. comparative properties of raney nickel proceeding from Ni-Ai intermetallic phases
TL;DR: Raney nickel catalysts, prepared from well defined pure phases, have been characterised by bulk composition, total and nickel surface areas, structure, activity and sensitivity to sulfur compounds as discussed by the authors.
Journal ArticleDOI
The nature of Raney nickel: VI. Transmission and scanning electron microscopy studies
TL;DR: In this paper, the authors examined Raney nickel by transmission electron microscopy but the scope of this study was limited by catalyst instability in the electron beam under normal operating conditions, and interpretable results were obtained with low electron beam irradiation of the specimen.
Journal ArticleDOI
Surface analysis of Raney catalysts
TL;DR: In this paper, the results obtained for Raney Ni catalysts of several types (types doped with Cr, Mo, and Cu) were compared with Raney Cu, which was examined for comparison, some of the samples were taken from catalysts that had already been used.
