Hydrogen Evolution at Liquid–Liquid Interfaces

Hubert Girault, Xile Hu, Heron Vrubel, Bin Su, Raheleh Partovi Nia, Imren Hatay

Blowing bubbles: Hydrogen evolution by proton reduction with [(C5Me5)2Fe] occurs at a soft interface between water and 1,2-dichloroethane (DCE). The reaction proceeds by proton transfer assisted by [(C5Me5)2Fe] across the water–DCE interface with subsequen ...

Three-Phase Catalytic Hydrogenation of a Functionalized Alkyne: Mass Transfer and Kinetic Studies with in Situ Hydrogen Monitoring

Albert Renken, Lioubov Kiwi, Martin Grasemann

Systematic studies of mass transfer interactions with intrinsic reaction kinetics were performed for the threephase selective hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE) over a modified Pd/CaC

Homogeneous catalytic decomposition of formic acid for high pressure hydrogen generation

Céline Fellay

The main obstacles in the widespread use of hydrogen as energetic alternative to fossil fuels are storage problems intrinsically linked to its extremely light and explosive nature. Since no ideal storage systems currently exist, reversible fixation of hydr ...

Electrocatalytic hydrogen evolution at positive potentials

Xile Hu

Hydrogen prodn. using earth abundant metals is one of the important challenges facing an energy economy based upon solar fuels. Schemes that incorporate the photo-oxidn. of water must also include schemes for efficiently converting released protons and ele ...

Hydrogen and coordination bonding supramolecular structures of trimesic acid on Cu(110)

Klaus Kern, Magalí Alejandra Lingenfelder, Giovanni Costantini

The adsorption of trimesic acid (TMA) on Cu(110) has been studied in the temperature range between 130 and 550 K and for coverages up to one monolayer. We combine scanning tunneling microscopy (STM), low-energy electron diffraction (LEED), reflection absor ...

Electrocatalytic hydrogen evolution by cobalt complexes of macrocyclic imine ligands

Xile Hu

A series of cobalt complexes with macrocyclic imine ligands such as difluoroboryldiglyxomime and [14]-Tetraene-N4 are synthesized for electrochem. hydrogen evolution catalysis. The complexes catalyze the redn. of proton to dihydrogen at potentials in the r ...

Mesoscopic thin films of hematite as photoanode for water photoelectrolysis

Alexis Joseph Duret

Due to the limiting amount of fossil fuel available and to the continuous growth of the world energy consumption, it becomes important to find alternative energy sources. Hydrogen produced by the photoelectrolysis of water is a perfect candidate as a clean ...

Periodic operation applied to the kinetic study of CO2 methanation

Albert Renken

Periodic operation was applied to CO2 hydrogenation to CH4 at 383 K on 2% Ru/TiO2. A continuous feed recycle reactor combined with a diffuse reflectance IR cell and a mass spectrometer was used to follow simultaneously the gas phase CO2 and CH4 as well as ...

Promoting effect of active carbons on methanol dehydrogenation on sodium carbonate - hydrogen spillover

Albert Renken

Methanol dehydrogenation to formaldehyde was conducted in a fixed-bed flow reactor with sodium carbonate catalyst mixed with active carbons or transition metals. The additives promoted the reaction rate at 880-970 K without modifying formaldehyde selectivi ...

Valence-Band States of Ion-Bombarded Polystyrene

Giorgio Margaritondo, György Foti

Ion-bombarded polystyrene with a 0.5-keV Ar+ beam has been investigated by means of photoelectron spectroscopy performed with synchrotron radiation. After a dose of 10(15) ions/cm2 the evolution of the valence band of the bombarded sample towards an amorph ...
