Gold–palladium core@shell nanoalloys: experiments and simulations por Spitale, Ana, Perez, M. A., Mejía Rosales, Sergio, Yacamán, Miguel José, Mariscal, Marcelo M.

“…Through aberration corrected-STEM, UV-vis spectroscopy and EDS chemical analysis, we were able to determine that Au(core)–Pd(shell) bimetallic nanoparticles were formed. Using different computational approaches, we were capable of establishing how the size of the core and the thickness of the shell will affect the thermodynamic stability of several core–shell nanoalloys. …”

Desorption of furfural from bimetallic Pt-Fe oxides/alumina catalysts por Dimas Rivera, Gloria Lourdes, De la Rosa, Javier, Lucio Ortiz, Carlos J., De los Reyes Heredia, José, González González, Virgilio Ángel, Hernández, Tomas

“…The mechanism of furfural desorption from the Pt-Fe/Al2O3 0.5%-0.5% sample was determined using physisorbed furfural instead of chemisorbed furfural; this mechanism involved the oxidation of the C=O group on furfural by the catalyst. The oxide nanoparticles on γ-Al2O3 support helped to stabilize the furfural molecule on the surface.…”
