Coupling electrokinetic with a cork-based permeable reactive barrier to prevent groundwater pollution: A case study on hexavalent chromium-contaminated soil
(Elsevier Ltd., 2022)
This work proposes an eco-efficient treatment technology for the remediation of a kaolinite-based clay soil artificially contaminated with hexavalent chromium (50 mg Cr(VI) kg–1 soil), combining electrokinetics (EK) with ...
Hydrogen evolution in acid solution at Pd electrodeposited onto Ti2AlC
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
The hydrogen evolution reaction (HER) was studied in 0.5 M H2SO4 at 25 degrees C on Pd electrodeposited onto Ti2AlC substrate, as an excellent substrate due to its high conductivity and high stability in concentrated ...
Methanol oxidation on an ink type electrode using Pt supported on high area carbons
(Pergamon-Elsevier Science Ltd, Oxford, 2001)
Methanol oxidation was investigated on the following Pt catalysts: bare Pt electrode, Pt covered by nafion (R) film, and pt catalysts supported on high area carbons in the form of an ink. The reaction was carried out using ...
Kinetic analysis of hydrogen evolution at Ni-Mo alloy electrodes
(Elsevier Science Ltd, 2000)
The hydrogen evolution reaction (HER) on Ni, Mo and MoNi intermetallic compound was investigated with ac impedance and dc polarization measurements in 1.0 mol dm-3 NaOH solution at 25 °C. The rate constants of the forward ...
Synthesis and characterization of MoOx-Pt/C and TiOx-Pt/C nano-catalysts for oxygen reduction
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
The oxygen reduction reaction (ORR) was studied at carbon supported MoOx-Pt/C and TiOx-Pt nanocatalysts in 0.5 mol dm(-3) HClO4 solution, at 25 degrees C. The MoOx-Pt/C and TiOx-Pt/C catalysts were prepared by the polyole ...
Incorporation of Pt, Ru and Pt-Ru nanoparticles into ordered mesoporous carbons for efficient oxygen reduction reaction in alkaline media
(Electrochimica Acta, 2015)
Ordered mesoporous carbon, volume-doped up to 3w.% with Pt, Ru and Pt-Ru nanoparticles was synthesized by evaporation-induced self-assembly method, under acidic conditions. The content of incorporated metal was determined ...
Oxygen reduction on iron-Part VI. Processes in alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 1994)
The kinetics of oxygen reduction were studied on passivated iron in borate buffered and unbuffered solutions of pH ranging from 7.4 to 13.8. A rotating disk electrode was employed. The O2 reduction on iron under these ...
Polarization curves in the ohmic controlled electrodeposition of metals
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
The conditions under which ohmic controlled metal electrodeposition occurs are discussed using a simple mathematical model. it is shown that ohmic controlled electrodeposition can be operative if the value of the exchange ...
Nb-TiO2 supported platinum nanocatalyst for oxygen reduction reaction in alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Platinum based nanocatalyst at home made Nb-TiO2 support was synthesized and characterized as the catalyst for oxygen reduction reaction in 0.1 mol dm(-3) NaOH, at 25 degrees C. Nb doped TiO2 catalyst support, containing ...
Ni-Sn coatings as cathodes for hydrogen evolution in alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
In this work the hydrogen evolution reaction (HER) at Ni-Sn alloy coatings, deposited onto Ni 40 mesh at different current densities from the bath containing 0.1 mol dm(-3) SnCl2 + 0.3 mol dm(-3) NiCl2 in the pyrophosphate-glycine ...
