A Comparative Study of Particle Size Distribution of Graphene Nanosheets Synthesized by an Ultrasound-Assisted Method
Amaro-Gahete, J.; Benítez, Almudena; Otero Izquierdo, Rocío; Esquivel, Dolores; Jiménez-Sanchidrián, César; Romero-Salguero, F.J.; Caballero Amores, Álvaro; Morales Palomino, Julián (MDPI, 2019)Graphene-based materials are highly interesting in virtue of their excellent chemical, physical and mechanical properties that make them extremely useful as privileged materials in different industrial applications. ... -
Aldol Condensation of Furfural with Acetone Over Mg/Al Mixed Oxides. Influence of Water and Synthesis Method
Parejas, A.; Cosano, Daniel; Hidalgo-Carrillo, J.; Ruiz, José Rafael; Marinas, Alberto; Jiménez-Sanchidrián, César; Urbano Navarro, Francisco José (MDPI, 2019)Aldol condensation of furfural and acetone (an important initial step to obtain diesel from biomass) was studied over MgAl mixed oxides. The influence of the utilization of microwaves and/or a surfactant (Pluronic 123) ... -
Análisis arqueométrico de los productos de corrosión de un caldero de bronce de baja época ibérica del Cerro de la Cruz (Almedinilla, Córdoba)
Mateos Luque, Laura Dara; Cosano, Daniel; Quesada Sanz, Fernando; Muñiz Jaén, Ignacio; Jiménez-Sanchidrián, César; Ruiz, José Rafael (Museo Histórico Municipal de Priego de Córdoba, 2017)Se estudian una serie de fragmentos de bronce de época ibérica hallados en el Cerro de la Cruz (Almedinilla, Córdoba) para determinar la composición química de los productos de corrosión formados sobre ellos. La caracterización ... -

Coumarin Derivatives Solvent-Free Synthesis under Microwave Irradiation over Heterogeneous Solid Catalysts
Bouasla, Souad; Amaro-Gahete, J.; Esquivel, Dolores; López, M. Isabel; Jiménez-Sanchidrián, César; Teguiche, Mabrouk; Romero-Salguero, F.J. (MDPI, 2017)A suitable methodology of synthesis of coumarin derivatives by Pechmann reaction over heterogeneous solid acid catalysts in a free solvent media under microwave irradiation is described. Resorcinol, phenol and ethyl ... -
Metal-Exchanged β Zeolites as Catalysts for the Conversion of Acetone to Hydrocarbons
Cruz-Cabeza, Aurora; Esquivel, Dolores; Jiménez-Sanchidrián, César; Romero-Salguero, F.J. (MDPI, 2012)Various metal-β zeolites have been synthesized under similar ion-exchange conditions. During the exchange process, the nature and acid strength of the used cations modified the composition and textural properties as well ... -
Preparation of Palladium-Supported Periodic Mesoporous Organosilicas and their Use as Catalysts in the Suzuki Cross-Coupling Reaction
Corral, Jorge A.; López, María I.; Esquivel, Dolores; Mora, Manuel; Jiménez-Sanchidrián, César; Romero-Salguero, F.J. (MDPI, 2013)Three periodic mesoporous materials, i.e., two organosilicas with either ethylene or phenylene bridges and one silica, have been used as supports for Pd nanoparticles. All Pd-supported samples (1.0 wt%) were prepared by ...
