Autor: Lucia M. Petkovic, Maria Fabiana Sardella, Cristina Deiana, Hugo S. Silva, Kyle C. Burch, Daniel M. Ginosar, Harry W. Rollins, Dolly Granados

Publikováno v: International Journal of Hydrogen Energy. 34:4057-4064

Seven activated carbon catalysts obtained from a variety of raw material sources and preparation methods were examined for their catalytic activity to decompose hydrogen iodide (HI) to produce hydrogen, a key reaction in the sulfur–iodine (S–I) t

Structure of hybrid (organic/inorganic) TiO2–SiO2 xerogels as studied by neopentane adsorption at 273 K and Ti K-edge X-ray absorption spectroscopy

Autor: Hugo S. Silva, Gustavo Larsen, Rosa Venturini de Silva

Publikováno v: Journal of Non-Crystalline Solids. 271:1-11

TiO2–SiO2 hybrid alcogels prepared from two different `organic silicon' precursors, namely Me2Si(OMe)2 and (Me2SiO)3, were characterized by adsorption of neopentane at 273 K and X-ray absorption spectroscopy (XAS) at the Ti K-edge. Simultaneous fit

Ethyl tert-Butyl Ether (ETBE) Synthesis on H-Mordenite: Gas-phase Kinetics and Drifts Studies

Autor: Manuel Márquez, Hugo S. Silva, Gustavo Larsen, Edgar Lotero

Publikováno v: Journal of Catalysis. 157:645-655

The ethyl tert-butyl ether (ETBE) formation between 313 and 363 K over an H-mordenite catalyst was studied in a packed-bed flow catalytic reactor at atmospheric pressure. An activation energy of 82 kJ/mol and reaction orders in isobutene and ethanol

Characterization of palladium supported on sulfated zirconia catalysts by DRIFTS, XAS and n-butane isomerization reaction in the presence of hydrogen

Autor: Hugo S. Silva, Ruben D. Parra, Lucia M. Petkovic, Edgar Lotero, Srinivasanallur Raghavan, Gustavo Larsen

Publikováno v: Applied Catalysis A: General. 130:213-226

Palladium supported on sulfated zirconia (PdSZ) has been characterized by the n-butane isomerization reaction in the presence of hydrogen, X-ray absorption spectroscopy (XAS) and diffuse reflectance Fourier transform infrared spectroscopy (DRIFTS) of

On a Simple Nonisothermal Adsorption Experiment with Organic Vapors and an Inertial Microbalance To Study the Surface Properties of Hybrid (Organic/Inorganic) Porous Materials

Autor: Rosa Venturini de Silva, Hugo S. Silva, Gustavo Larsen

Publikováno v: Journal of colloid and interface science. 224(1)

A nonisothermal adsorption experiment using a controlled flow of cyclopentane in the 333-313 K range is used to simultaneously estimate the specific surface area and micropore volume of a hybrid (organic/inorganic) alcogel. For reference, the method
