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 ... -
Highly modulated supported triazolium-based ionic liquids: direct control of the electronic environment on Cu nanoparticles
Valdebenito, Cristian [Chile. Universidad Mayor. Facultad de Ciencias. Centro de Nanotecnología Aplicada]; Pinto, José; Nazarkovsky, Michael; Chacón, Gustavo; Martínez-Ferrate, Oriol; Wrighton-Araneda, Kerry; Cortés-Arriagada, Diego; Camarada, María Belen [Chile. Universidad Mayor. Facultad de Ciencias. Centro de Nanotecnología Aplicada]; Fernandes, Alves Jesum; Abarca, Gabriel [Chile. Universidad Mayor. Facultad de Ciencias. Centro de Nanotecnología Aplicada] (Royal Society of Chemistry, 2020-03-01)A series of new triazolium-based supported ionic liquids (SILPs), decorated with Cu NPs, were successfully prepared and applied to the N-arylation of aryl halides with anilines. The triazoles moieties were functionalised ... -
Interaction of supported ionic liquids phases onto copper nanoparticles: A DFT study
Wrighton-Araneda, Kerry; Valdebenito, Cristian; Camarada, María B. [Chile. Universidad Mayor. Facultad de Ciencias, Centro de Nanotecnología Aplicada]; Abarca, Gabriel; Cortés-Arriagada, Diego (Elsevier, 2020-07-15)The interaction between Supported Ionic Liquids Phases (SILPs) based on triazole and copper nanoparticles was investigated using density functional theory calculations. Three triazolium cations (T1(+), T2(+), and T3(+)) ...
