Selective electrocatalytic hydrogenation using palladium nanoparticles electrochemically formed in layer-by-layer multilayer films
(Royal Society of Chemistry, 2015-04)
Sequential adsorption of PdCl42- within weak polyelectrolyte layer-by-layer (LbL) self-assembled multilayer films with further electrochemical reduction to yield Pd0 nanoparticles (Pd-NPs) has been demonstrated. The ...
Polyethylenimine functionalized with dopamine: Characterization and electrocatalytic properties
(Wiley VCH Verlag, 2010-06)
We report the chemical modification of polyethylenimine (PEI) by functionalization with dopamine (Do) using glutaraldehyde (Glu) as a linker (PEI-Glu-Do). The new polymer was characterized by FT-IR spectroscopy, by derivative ...
Surfactant presence in a multilayer polyelectrolyte-enzyme system improves its catalytic response
(Elsevier Science Inc, 2009-05)
Self-assembling of poly(allylamine) containing an osmium polypyridil complex (PAOs) alternatively with sodium dodecyl sulfate (SDS) and glucose oxidase (GOx) generates a ternary multilayer system, (PAOs/SDS/PAOs/GOx)n. The ...
Gold nanoparticles supported in zirconia-ceria mesoporous thin films: A highly active reusable heterogeneous nanocatalyst
(American Chemical Society, 2015-01)
Gold nanoparticles (NP) trapped in the mesopores of mixed zirconia-ceria thin films are prepared in a straightforward and reproducible way. The films exhibit enhanced stability and excellent catalytic activity in nitro-group ...
Analysis of the hydrogen electrode reaction mechanism in thin-layer cells. 1. Theory
(Elsevier Science Sa, 2010-12)
This work develops the equations that relate the kinetic parameters of the hydrogen electrode reaction (HER) with the current density (j) vs. potential (E) dependences of a thin-layer cell (TLC). Two operation modes of the ...
The Structure of the Cobalt Oxide/Au Catalyst Interface in Electrochemical Water Splitting
(Wiley VCH Verlag, 2018-09)
The catalytic synergy between cobalt oxide and gold leads to strong promotion of the oxygen evolution reaction (OER)—one half-reaction of electrochemical water splitting. However, the mechanism behind the enhancement effect ...
Performance of cuprous oxide mesoparticles with different morphologies as catalysts in a carbon nanotube ink for printing electrochemical sensors
(Elsevier Science SA, 2020-12)
A simplified, surfactant-free method is presented for the synthesis of cuprous oxide mesoparticles involving the use of only three reactants at room temperature. Different morphologies, such as cubes, cuboctahedra, truncated ...
Waterborne carbon nanotube ink for the preparation of electrodes with applications in electrocatalysis and enzymatic biosensing
(Pergamon-Elsevier Science Ltd, 2018-10)
Conductive inks with optimal properties for amperometric sensor fabrication are key materials for low cost and high performance electrodes printed on flexible substrates. In this work, electrodes made with a carbon nanotube ...
Electrochemical stability of the reconstructed Fe3O4(001) surface
(Wiley-VCH, 2020-12-01)
Establishing the atomic-scale structure of metaloxide surfaces during electrochemical reactions is a key step to modeling this important class of electrocatalysts. Here, we demonstrate that the characteristic (p2p2)R458 ...
Insight into the Mechanism of Oxygen Reduction Reaction on Micro/Mesoporous Carbons: Ultramicropores versus Nitrogen-Containing Catalytic Centers in Ordered Pore Structure
(American Chemical Society, 2019-10)
Ordered mesoporous/microporous carbon was synthesized from sucrose. The carbon was oxidized and modified with urea at 600, 800, and 950 °C. The obtained carbons differed in the pore size distributions in the meso- and ...
