Publikováno v: Topics in Catalysis. 62:977-988

Monometallic gold and iridium, and bimetallic gold–iridium on ceria–niobia (Nb2O5–CeO2) catalysts were synthesized by deposition–precipitation with urea. Ceria–niobia support, synthesized by co-precipitation, presented a higher reducibility

On the Surface Nature of Bimetallic PdZn Particles Supported on a ZnO–CeO2 Nanocomposite for the Methanol Steam Reforming Reaction

Autor: Marta Verónica Bosco, Miguel Angel Baltanas, Adrian Lionel Bonivardi, Celina Barrios

Publikováno v: Catalysis Letters. 148:2233-2246

CO adsorption—as a molecular probe—was studied by transmission IR spectroscopy on pre-reduced Pd and bimetallic PdZn nanoparticles. Palladium was supported (2 wt% Pd) on pure CeO2, ZnO and a ZnO–CeO2 composite (atomic ratio Zn:Ce = 1:2). The Pd
