(Elsevier Ltd, 1998)Cobalt phthalocyanine (CoPc) and cobalt naphthalocyanine (CoNPc) exhibit different redox and electronic properties. Redox processes on CoPc are more reversible than on CoNPc. The pH dependence of those processes is also ...
-
(Elsevier, 2000)Recent literature results on inorganic models related to metalloenzymes which transport electrons or activate small molecules are discussed in this review. The molecular systems are essentially restricted to macrocyclic ...
-
(Springer, 2016)We report that glassy carbon electrode (GCE) modified with multiwalled carbon nanotubes (MWCNTs) can encapsulate or entrap 3,5-dinitrobenzoic acid (35DNB) generating a 35DNB-MWCNTGC electrode. After electrochemical reduction ...
-
(Elsevier, 2015)Rhenium oxides are materials of interest for applications in the catalysis of reactions such as those occurring in fuel cells and photoelectrochemical cells. This research work was devoted to the production of rhenium oxide ...
-
(Wiley-VCH Verlag, 2018)We report the advantages of hybrid nanomaterials prepared with electrogenerated ferrites (MFe2O4; M: Co, Mn) and multi-walled carbon nanotubes (MWCNTs) or thermally reduced graphene oxide (TRGO) on the electro-reduction ...
-
(Elsevier, 2020)In this work, we have both synthesized and studied 4-phenylbutyl-3,5-dinitrobenzoate (3,5-DNBPh) as a potential precursor of an electrocatalytic mediator for the oxidation of NADH, with the di-nitro compound immobilized ...
-
(Elsevier B.V., 2019)In a previous study, we revealed a new way to modify multi-walled carbon nanotubes (MWCNTs) with 3,5-dinitrobenzoic acid (35DNB). Furthermore, we proved that a 35DNB-MWCNTGC electrode efficiently catalysed the oxidation ...
-
(Elsevier Ltd, 2011)This paper describes the electrochemical reduction of nitrite ion in neutral aqueous solution mediated by tetraruthenated metalloporphyrins (Co(II), Ni(II) and Zn(II)) electrostatically assembled onto a Nafion film previously ...
-
(Wiley, 2018)Gold nanoparticles (AuNPs) have unique properties, making them attractive for electronic and energy-conversion devices and as (electro)catalysts for electrochemical sensors. In addition to the size and shape of AuNPs, the ...
-
(Elsevier B.V., 2014)The preparation of an ITO (Indium Tin Oxide) modified electrode with a mixed valence CoIII/FeII complex is described. The ITO electrode was initially modified with Au nanoparticles by dip coating in order to obtain and ...
-
(Wiley, 2017)This work describes the electrochemical reduction of carbon dioxide in aqueous solution mediated by tetraruthenated metal-loporphyrins (TRP; Co(II) and Zn(II)) in Nafion (Nf) and polyvinyl chloride (PVC) as a support. The ...
-
(2011)A new conducting film derived from the complex [Fe (diaphen)3]2+, (diaphen=5,6-diamino-1,10-phenanthroline) was electropolymerized by cyclic voltammetry onto a glassy carbon electrode. Poly-[FeII (diaphen)3] was studied ...
-
(Sociedad Chilena de Quimica, 2007)This paper describes the electrochemical reduction of nitrite ion in basic media 0.2M KHC03, with glassy carbon or ITO electrodes modified with a conducting polymer derived from Co(II)tetra-3-aminophenyl-porphyrin. Cyclic ...
-
(Wiley & Sons, 2015)The incorporation of carbon nanotubes to a Nafion/tetraruthenated cobalt porphyrin/glassy carbon electrode (GC/Nf/CoTRP vs GC/Nf/CNTCoTRP) enhanced the amperometric determination of hydrogen peroxide. Both electrodes ...
-
(Wiley-VCH Verlag, 2019)A novel and useful method to catalyze the electro-oxidation of nicotinamide adenine dinucleotide (NADH) over a glassy carbon electrode (GCE) modified with graphene oxide (GO) is presented. Based on the presence of oxygen ...
-
(Elsevier, 2020)Iron(II) 2,3,9,10,16,17,23,24-octa(cyano)phthalocyanine (OCNFePc), was tested as a catalyst for the oxygen reduction reaction (ORR) adsorbed on carbon nanotubes. The composite was analyzed spectroscopically and electrochemically ...
-
(2009)The complex [FeII(Imz-phen)3](PF6)2, (Imz-phen = imidazolidine-[4,5-f]-1,10-phenanthroline) has been prepared and characterized using X-ray diffraction, UV–vis and IR spectroscopy, elemental analysis, fast atomic bombardment ...
