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

“…In this work, the desorption of furfural, which is a competitive intermediate during the production of biofuel and valuable aromatic compounds, was studied using pure alumina, as well as alumina impregnated with iron and platinum oxides both individually and in combination, using thermogravimetric analysis (TGA). The bimetallic sample exhibited the lowest desorption percentage for furfural. …”

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. …”
