On the new low-dimensional organic–inorganic hybrid solids Cu4(bipy)4[V4P2O19]·nH2O (n ~ 5) and Cu2(bipy)2[V2P2O12] with linear [V4P2O19]8- and cyclic [V2P2O12]4-oligomers
(2005)
The new hybrid organic–inorganic copper oxovanadium phosphates of composition Cu4(bipy)4V4O11(PO4)2·nH2O (n 5) (1) and Cu2(bipy)2V2P2O12 (2) (bipy = 2, 2′-bipyridine) adopting the triclinic symmetry were obtained by soft ...
Weak C-H center dot center dot center dot O interactions leading to measurable effects in polymeric sulfates [M(SO4)L(H2O)(2)](n) (M = Cd, Zn, Cu; L = bipy, phen, dmp)
(2003)
The structure of two sulfate complexes, [Zn(SO4)phen(H2O)2]n and [Cd(SO4)bipy(H2O)2]n, are presented. They are polymeric and isomorphous to an homologous series already reported, namely [Zn(SO4)bipy(H2O)2]n, [Cd(SO4)dmph(H2O)2]n, ...
Comparative study of water and carbon dioxide adsorption on CuFeO2 and CuFe1-xGaxO2 highly epitaxial thin films
(2016)
Thermal programmed desorption (TPD) of CO2 and H2O from a 200 nm thick CuFeO2 and 52 nm thick CuFe1-xGaxO2 delafossite surfaces was performed in a Ultra-high vacuum (UHV) chamber. The thin films with epitaxial quality were ...
Obtenção de nanossistemas magnéticos através de blocos construtores com o ligante bis(2-piridilcarbonil)-amideto (bpca)
(Universidade Federal de Minas GeraisUFMG, 2010-02-23)
In this work was carried out the synthesis of trinuclear compounds and bimetallic systems, being their magnetic properties studied. In addition, new inorganic complexes were prepared in an attempt to use them as a bridge ...
Nanopartículas de CuO y su propiedad antimicrobiana en cepas intrahospitalarias
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Química, 2017-09-01)
Empleando un prototipo de reactor, se sintetizaron nanopartículas (NPs) de CuO a través del método de precipitación a partir de CuSO2·5H2O y de Cu(CH3COO)2·H2O. Las NPs obtenidas fueron caracterizadas mediante XRD, FT-IR, ...
Monoliths washcoated with AuCu catalysts for CO removal in an ethanol fuel processor: Effect of CeO2–SiO2 dual support on the catalytic performance and reactor costMonolitos revestidos con catalizadores de AuCu para la eliminación de CO en un procesador de combustible de etanol: efecto del soporte dual CeO2-SiO2 en el rendimiento catalítico y el costo del reactor
(International Journal of Hydrogen Energy, 01/06/2020)
CO removal from a syngas was evaluated in a single catalytic unit using structured AuCu/CeO2–SiO2 catalysts. Initially, AuCu/CeO2–SiO2 powder catalysts with several SiO2 loadings (0–100 mol%) were assessed. SiO2 addition ...
Thermal stability of the cu-ceo2 interface on silica and alumina, and its relation with activity in the oxidation reaction of co and the decomposition of n2o
(Sociedad Chilena de Quimica, 2018)
The effect of the support on the formation of the Cu-CeO2
interface and its thermal stability after calcination at 500, 700 and 900 ºC is studied. The supports
used are SiO2
, because of its inert character, and ...
Comparative study of two chemically isostructural polymers: [Cu-2(VO2)(HPO4)(2)(NO3)(bpy)(2)]center dot 2H(2)O/H3PO4 (bpy is 2,2 '-bipyridine)
(2004)
The crystal structure of copper compound, [Cu2(VO 2)(HPO4)2 (NO3)(bpy)2].X was studied. These chemically isostructural systems were obtained by hydrothermal methods, which differ in the solvate molecules stabilizing the ...
