Copper-doped titania photocatalysts for simultaneous reduction of CO2 and production of H2 from aqueous sulfide
Gonell, Francisco; Puga, Alberto V.; Julian-Lopez, Beatriz; García Gómez, Hermenegildo; CORMA, AVELINO Elsevier (2016-01)Copper-doped titanium dioxide materials with anatase phase (Cu-TiO2, atomic Cu contents ranging from 0 to 3% relative to the sum of Cu and Ti), and particle sizes of 12–15 nm, were synthesised by a solvo-thermal method ... -
Effect of the Cα substitution on the ketonic decarboxylation of carboxylic acids over m-ZrO2: the role of entropy
Oliver-Tomas, B.; Gonell, Francisco; Pulido, A.; Renz, M.; Boronat, M. Royal Society of Chemistry (2016)The kinetics of the ketonic decarboxylation of linear and branched carboxylic acids over m-ZrO2 as a catalyst has been investigated. The same apparent activation energy is experimentally determined for the ketonic deca ... -
Key insights on the structural characterization of textured Er2O3–ZrO2 nano-oxides prepared by a surfactant-free solvothermal route
Julian-Lopez, Beatriz; De la Luz, Verónica; Gonell, Francisco; Cordoncillo, Eloisa; López-Haro, Miguel; Calvino, Jose J.; Escribano López, Purificación Elsevier (2012)Zirconia-mixed oxides can exhibit cubic fluorite and pyrochlore structure. Their discrimination is not easy in nanooxides with a crystal size close to that of a few unit cells. In this work, high resolution transmission ... -
One step microwave-assisted synthesis of nanocrystalline WOx–ZrO2 acid catalysts
Gonell, Francisco; Portehault, David; Julian-Lopez, Beatriz; Vallé, Karine; Sánchez, Clément; CORMA, AVELINO Royal Society of Chemistry (2016)Nanocrystalline ZrO2 and WOx–ZrO2 catalysts with good control over the zirconia phase and the nature of the W species were synthesized by a microwave-assisted aqueous route.
