Morère, Jacobo ; Royuela, Sergio ; Asensio, Guillermo ; Enciso, Eduardo ; Pando, Concepción ; Cabañas Poveda, Albertina | The Royal Society of London | 2015-11-16The deposition of Ni nanoparticles into porous supports is very important in catalysis. In this paper, we explore the use of supercritical CO2 (scCO2) as a green solvent to deposit Ni nanoparticles on mesoporous SiO2 SBA-15 and a carbon xerogel.[...]texto impreso
Castro, Alichandra ; Morère, Jacobo ; Cabañas Poveda, Albertina ; Ferreira, Liliana ; Godinho, Margarita ; Ferreira, Paula ; Vilarinho, Paula | RSC | 2016-12A new concept to prepare nanocomposite thin films is explored. Two chemical-based bottom-up steps are used to design functional films including: i) block copolymerassisted self-assembly of a porous matrix; and ii) impregnation of nanoparticles f[...]texto impreso
Sánchez Miguel, E. ; Tenorio, María José ; Morère, Jacobo ; Cabañas Poveda, Albertina | Elsevier | 2017-12Sustainability is emerging as design criteria in catalysts production. Hence, the preparation of Pt bimetallic catalysts using supercritical CO2 (scCO2) as a green solvent is proposed. PtRu and PtCu nanoparticles (NPs) were deposited on mesoporo[...]texto impreso

Chamorro, Elena ; Tenorio, M. José ; Calvo Garrido, Lourdes ; Torralvo Fernández, María José ; Sáez Puche, Regino ; Cabañas Poveda, Albertina | Elsevier | 2020-05Superparamagnetic iron oxide nanoparticles (SPIONs) supported on high surface area mesoporous SiO2 are advanced materials of great interest in catalysis, adsorption and biomedicine. Here we present a new process to prepare SPION/SiO2 materials b[...]texto impreso
Cuadra Mendoza, Isaac Alfonso ; Martínez Casado, Francisco Javier ; Rodriguez Cheda, Jose A. ; Redondo, M.I. ; Pando, Concepción ; Cabañas Poveda, Albertina | ACS | 2019A new adduct of isonicotinamide (INA) with copper(II) propanoate [Cu(C3)2] was prepared [Cu2(C3)4(INA)4] using two different methods. This type of compound shows high fungicidal activity. Solvent evaporation from ethanol rendered crystals suitab[...]texto impreso
Tenorio, María José ; Ginés, Sonia ; Pando, Concepción ; Rodríguez Renuncio, José Antonio ; Cabañas Poveda, Albertina | ACS | 2017-11-21The solubility of Ni(NO3)2?6H2O in high-pressure CO2 + ethanol mixtures was measured using a high-pressure variable-volume view cell from (308.2 to 353.2 K) and up to 25.0 MPa. This compound has been used previously as a Ni precursor in metal de[...]texto impreso
Morère Rodríguez, Jacobo ; Torralvo Fernández, María José ; Pando García-Pumarino, Concepción ; Rodríguez Renuncio, Juan Antonio ; Cabañas Poveda, Albertina | RSC | 2015Ru nanoparticles were successfully deposited into mesoporous SiO2 SBA-15 using supercritical CO2 (scCO2). The use of scCO2 favoured the metal dispersion and Ru nanoparticles uniformly distributed throughout the support were obtained. Different p[...]texto impreso
Tenorio, M.J. ; Carnerero, C. ; Torralvo Fernández, María José ; Pando García-Pumarino, Concepción ; Cabañas Poveda, Albertina | Elsevier | 2018-08-02Chemical modification of mesoporous SiO2 SBA-15 with thiol groups was performed using mercaptopropyltrimethoxysilane (MPTMS) dissolved in supercritical CO2 (scCO2). Thiol groups serve as adsorbents for the selective removal of contaminant metal [...]
