Journal ArticleDOI
Some recent results on metal/support interaction effects in NM/CeO2 (NM: noble metal) catalysts
S. Bernal,José J. Calvino,Miguel A. Cauqui,José M. Gatica,C. Larese,J.A. Pérez Omil,José M. Pintado +6 more
TL;DR: In this article, a proposal is made about the nature of the metal/support interaction phenomena occurring in ceria-supported noble metal (NM/CeO2) catalysts as the reduction temperature is increased.
Journal ArticleDOI
The interpretation of HREM images of supported metal catalysts using image simulation : profile view images
S. Bernal,F.J. Botana,José J. Calvino,Carlos López-Cartes,José A. Pérez-Omil,José M. Rodríguez-Izquierdo +5 more
TL;DR: In this article, the authors focus on the analysis of profile view images with reference to the fine details of the contrasts both in the metal particles and in the outer support layers, and prove that complex contrasts which very often appear in the images can be interpreted on the grounds of the structural features of the catalysts and on the recording conditions in the microscope.
Journal ArticleDOI
Preparation and characterization of a praseodymium oxide to be used as a catalytic support
TL;DR: In this paper, the preparation and characterization of a praseodymia sample to be used as a support for highly dispersed metals is described. Butts et al. showed that the oxide sample was prepared by decomposing in a flow of helium, at 973 K, the phase obtained by precipitation with ammonia from a solution of Pr(NO3)3.

Some Recent Results on Metal/Support Interaction Effects in NM/CeO2 (NM Noble Metal) Catalysts
S. Bernal,José J. Calvino,Miguel A. Cauqui,José M. Gatica,C. Larese,J.A. Pérez Omil,José M. Pintado +6 more
TL;DR: In this paper, the nature of the metal/support interaction phenomena occurring in ceria-supported noble metal (NM/CeO2; NM: Rh, Pd, Pt) catalysts is discussed.
