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
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 [...]
