    • Building Pyridinium Molecular Wires as Axial Ligands for Tuning the Electrocatalytic Activity of Iron Phthalocyanines for the Oxygen Reduction Reaction 

      Abarca, Gabriel [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada]; Pizarro, Ana; Gutíérrez-Cerón, Cristián; Cortés-Arriagada, Diego; Bernardi, Fabiano; Berrios, Cristhian; Silva, Juan F.; Rezende, Marcos C.; Zagal, José H.; Onate, Rubén; Ponce, Ingrid (AMER CHEMICAL SOC, 2018)
      We have been able to"tune"the electrocatalytic activity of iron phthalocyanine (FePc) and iron hexadodeca-chlorophthalocyanine (16(Cl)FePc) for the oxygen reduction reaction (ORR) by manipulating the"pull effect"of pyridinium ...
    • Structural, electronic and catalytic properties of palladium nanoparticles supported on poly(ionic liquid) 

      Abarca, Gabriel [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada]; Simon, Nathalia M.; Scholten, Jackson D.; Domingos, Josiel B.; Mecerreyes, David; Dupont, Jairton (ELSEVIER SCIENCE BV, 2018)
      The structural, electronic and support effect on palladium nanoparticles (Pd NPs) prepared by sputtering deposition and chemical reduction of a Pd(II) precursor in/on a poly(ionic liquid) (PIL) was investigated in the ...
    • Tuning the structure and magnetic behavior of Ni-Ir-based nanoparticles in ionic liquids 

      Abarca, Gabriel [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada]; da Silva, Kacris I. M.; Bernardi, Fabiano; Baptista, Daniel L.; Leite Santos, Marcos José; Fernández Barquin, Luis; Dupont, Jairton; de Pedro, Imanol (ROYAL SOC CHEMISTRY, 2018)
      We report on a simple preparation of extremely small diameter (ca. 2 nm) Ni-Ir-based NPs using Ni(COD)(2) and [Ir(COD)OCH3](2) in 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (BMImNTf(2)). The prepared NPs ...
