Cobalt, Iron, and Manganese Metallocorroles in Catalytic Oxidation of Water. An Overview of the Synthesis, Selected Redox and Electronic Properties, and Catalytic Activities
(Wiley VCH Verlag, 2021-11)
Metallocorroles have emerged as interesting and versatile catalysts for a variety of redox reactions. These include clean-energy related small-molecule activation reactions such as proton, carbon dioxide and dioxygen ...
Electrochemical Desorption of Thiolates and Sulfur from Nanoparticle and Planar Platinum Surfaces
(American Chemical Society, 2013-03-25)
Thiolate-protected platinum nanoparticles have become promising for applications in heterogeneous catalysis and the fabrication of new materials for hydrogen storage. Once nanoparticles have been synthesized and conveniently ...
Synthesis and Performance of Nickel/Reduced Graphene Oxide Hybrid for Hydrogen Evolution Reaction
(Springer New York LLC, 2018-01)
In this work, a simple and reproducible method for the syntheses of hybrid nickel/reduced graphene oxide electrodes is presented. This method consists in a direct modification of a conventional nickel electrodeposition ...
Adsorción de aniones en electrodos nanoestructurados de Ag sobre HOPGAdsorption of anions on Ag nanostructured electrodes on HOPG
(Universidade Federal do Rio de Janeiro, 2018-07-19)
La estructura y propiedades de la interfase electroquímica, son el resultado de las interacciones que se producen entre los distintos componentes de una solución electrolítica y el electrodo metálico. En particular, las ...
Oxygen Reduction in Alkaline Media—a Discussion
(Springer New York LLC, 2017-11)
We propose a complete reaction sequence for oxygen reduction in alkaline solutions, in which the first two steps occur in the outer sphere mode. The oxygen-oxygen bond is broken in the third step, which involves adsorption ...
Ni and NixCoy alloys electrodeposited on stainless steel AISI 316L for hydrogen evolution reaction
(Springer New York LLC, 2018-07)
NixCoy electrocatalysts for hydrogen evolution reaction (HER) were synthesized by electrodeposition on AISI 316L stainless steel (denoted as SS316L), as a scalable and economical alternative to be used in alkaline ...
Study of the Formic Acid Electrooxidation on Rhodium on Steady State Using a Flow Cell: Potential Dependence of the CO Coverage
(Springer, 2020-04)
The HCOOH electrooxidation reaction (FAO) was experimentally studied on rhodium electrode using a flow cell in a 0.5-MHCOOH + 0.5-M H2SO4 solution. It was obtained the steady-state current-potential curve by chronoamperometry, ...
Enhanced hydrogen evolution activity of Ni[MoS2] hybrids in alkaline electrolyte
(Springer, 2020-05)
In this paper is presented a simple one-pot synthesis of a composite electrode with a non-noble metal for the catalysis of hydrogen evolution reaction in alkaline media. The Ni[MoS2] composite electrocatalyst has been ...
Effect of Nitrogen-Functional Groups on the ORR Activity of Activated Carbon Fiber-Polypyrrole-Based Electrodes
(Springer, 2018-07-10)
Polypyrrole (PPy) coatings inside the microporosity of an activated carbon fiber (ACF) were synthesized by chemical polymerization obtaining ACF-PPy composites. N-doped ACFs were prepared by carbonization of the ACF-PPy ...
The Role of Surface Functionalities in PtGe and PtIn Catalysts for Direct Methanol Fuel Cells
(Springer New York LLC, 2019-03)
Bimetallic PtGe and PtIn catalysts were prepared over Vulcan carbon (VC) and multiwall carbon nanotubes (NT) by conventional impregnation method (CI). These supports were functionalized with citric or nitric acid. The ...
