Gold catalyzes the Sonogashira coupling reaction without the requirement of palladium impurities

Corma Canós, Avelino; Juárez Marín, Raquel; Boronat Zaragoza, Mercedes; Sánchez, Félix; Iglesias, Marta; García Gómez, Hermenegildo (Royal Society of Chemistry, 2011)

[EN] By a combination of kinetic and theoretical studies it is concluded that gold is intrinsically active to perform the Sonogashira coupling reaction between phenylacetylene and iodobenzene. The presence of Pd impurities ...
Incorporation of Mesoporous Silica Particles in Gelatine Gels: Effect of Particle Type and Surface Modification on Physical Properties

Pérez-Esteve, Édgar; Oliver Hernández, Laura; García López, Laura; Nieuwland, Maaike; de Jongh, Harmen H. J.; Martínez-Máñez, Ramón; Barat Baviera, José Manuel (American Chemical Society, 2014-06-17)

The aim of this work was to investigate the impact of mesoporous silica particles (MSPs) on the physicochemical properties of filled protein gels. We have studied the effect of the addition of different mesoporous silica ...
Making C-C bond with gold catalysts: A theoretical study of the influence of gold particle size on the dissociation of the C-X bond in aryl halides

Boronat Zaragoza, Mercedes; López Auséns, Javier Tirso; Corma Canós, Avelino (American Chemical Society, 2014-05-01)

The adsorption and activation of iodo-, bromo-, and chlorobenzene over gold catalysts of different size, including an extended Au(111) surface; three-dimensional Au38 and Au13 nanoparticles; and planar Au7, Au6, and Au3 ...
Making C-C bonds with gold: identification of selective gold sites for homo- and cross-coupling reactions between iodobenzene and alkynes

Boronat Zaragoza, Mercedes; Cómbita Merchán, Diego Fernando; Concepción Heydorn, Patricia; Corma Canós, Avelino; García Gómez, Hermenegildo; Juárez Marín, Raquel; Laursen ., Siris Odin; Lopez-Castro, Juan de Dios (American Chemical Society, 2012-11-29)

The nature of the active sites involved in the gold catalyzed Sonogashira cross-coupling reaction between iodobenzene and phenylacetylene, and in the competitive homocoupling reactions, has been investigated by means of ...
Photocatalytic water gas shift using visible or simulated solar light for the efficient, room-temperature hydrogen generation

Sastre Calabuig, Francesc; Oteri, Marica; Corma Canós, Avelino; García Gómez, Hermenegildo (Royal Society of Chemistry, 2013-07)

Gold nanoparticles supported on P25 TiO2 act as highly efficient photocatalysts for promoting the simultaneous H2O reduction to H-2 and CO oxidation to CO2. This photocatalytic process can be performed using simulated solar ...
Preparation of graphene quantum dots from pyrolyzed alginate

Atienzar Corvillo, Pedro Enrique; Primo Arnau, Ana María; Lavorato, Cristina; Molinari, Raffaele; García Gómez, Hermenegildo (American Chemical Society, 2013)

Pyrolysis at 900 degrees C under an inert atmosphere of alginate, a natural widely available biopolymer, renders a graphitic carbon that upon ablation by exposure to a pulsed 532 nm laser (7 ns, 50 mJ pulse(-1)) in ...
Selective and Sensitive Chromogenic Detection of Trivalent Metal Cations in Water

Lozano-Torres, Beatriz; El Sayed Shehata Nasr, Sameh; Costero, Ana M.; Gil, Salvador; Parra, Margarita; Martínez-Máñez, Ramón; Sancenón Galarza, Félix (Chemical Society of Japan, 2016-04-15)
