  • Synthesis and characterization of new composites: PANI/Na-AlSBA-3 and PANI/Na-AlSBA-16 

    Martínez, María Laura; Luna D´Amicis, Froilán A.; Beltramone, Andrea Raquel; Gómez Costa, Marcos Bruno; Anunziata, Oscar Alfredo (2011)
    The new aluminosilicate materials (Na-AlSBA-3 and Na-AlSBA-16) were synthesized for application in the preparation of composites. Silica mesoporous materials were obtained following the sol–gel method and post-synthesis ...

  • Synthesis of ordered mesoporous SBA-3 materials using silica gel as silica source 

    Martínez, María Laura; Ponte, María Virginia; Anunziata, Oscar Alfredo; Beltramone, Andrea Raquel (2014)
    Nanostructured materials have exceptional and highly attractive properties, including catalyst, adsor- bent, separation media and chemo sensor. Technical advances in these fields require the development of ordered porous ...

  • Synthesis, characterization and catalytic performance of bimetallic Ir-Pt catalysts for tetralin hydrogenation 

    Vallés, Verónica; Ledesma, Brenda; Rivoira, Lorena Paola; Cussa, Jorgelina; Martínez, María Laura; Anunziata, Oscar Alfredo; Beltramone, Andrea Raquel (2014)
    Bimetallic Pt–Pd catalysts have received considerable attention, because they show high activity in a variety of catalytic applications (1) and stability compared with monometallic Pt or Pd catalysts. For instance, the ...

  • Synthesis, characterization and hydrotreating activity of Ir catalysts supported on titania-modified mesoporous material 

    Ledesma, Brenda; Vallés, Verónica; Rivoira, Lorena Paola; Martínez, María Laura; Anunziata, Oscar Alfredo; Beltramone, Andrea Raquel (2014)
    A titanium modified catalyst based on noble metal has been prepared with the main aim of obtaining Nitrogen-tolerant catalysts to be used in second stage processes of mild-hydrotreating. We study the catalytic properties ...

  • Titania-modifed SBA-16 applied to oxidative desulfuration of DBT 

    Rivoira, Lorena Paola; Vallés, Verónica; Ledesma, Brenda; Martínez, María Laura; Anunziata, Oscar Alfredo; Beltramone, Andrea Raquel (2014)
    Recent results show that Ti-containing molecular sieves exhibit good catalytic reactivity in the oxidation of sulfide, mercaptan, thiophene and derivatives [1]. In this work, we describe the preparation and characterization ...

  • XANES-PCA analysis of Ti-species in MCM-41 mesoporous silica synthesized by different methods 

    Anunziata, Oscar Alfredo; Beltramone, Andrea Raquel; Martínez, María Laura; Giovanetti, Lisandro J.; Requejo, Félix G.; Ledec, Eduardo (2011)
    MCM-41 mesoporous silica was prepared with Ti incorporated in the structure by two different ways: hydrothermal and atmospheric pressure by sol–gel method. To evaluate each synthesis, these materials were in situ investigated ...
