Hydrogen evolution at polarised liquid/liquid interfaces catalyzed by molybdenum disulfide

Hubert Girault, Xile Hu, Heron Vrubel, Peiyu Ge, Imren Hatay

Molybdenum disulfide microparticles in suspension in an aqueous acidic solution adsorb at the interface with an organic electrolyte solution containing the reducing agent, decamethylferrocene, to catalyse hydrogen evolution. This catalytic process has been ...

Hydrogen Storage and Delivery: The Carbon Dioxide – Formic Acid Couple

Gabor Laurenczy

Carbon dioxide and the carbonates, the available natural C-1 sources, can be easily hydrogenated into formic acid and formates in water; the rate of this reduction strongly depends on the pH of the solution. This reaction is catalysed by ruthenium(II) pre- ...

Hydrogen evolution catalyzed by electrodeposited nanoparticles at the liquid/liquid interface

Hubert Girault, Manuel Alejandro Méndez Agudelo, Peiyu Ge, Imren Hatay, Joonas Jalmari Nieminen

Aqueous protons reduction by decamethylferrocene in 1,2-dichloroethane can be catalyzed efficiently by platinum and palladium nanoparticles electrogenerated in situ at the liquid–liquid interface. ...

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 ...

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 ...

Hydroxylamine decomposition in the presence of iron studied by calorimetry, online mid-IR and UV-vis spectroscopy

Julien Léo Billeter, Konrad Hungerbühler

Recent explosions at two chemical plants, one in the United States and one in Japan, involving hydroxylamine manufacture underline the lack of mechanistic understanding about this industrially relevant compound. The basic chemical properties of hydroxylami ...

2006

As part of a collaborative, NSF-supported initiative to help develop the basic chem. needed for producing solar fuels, our group has been studying relatively inexpensive, first row transition metals that mediate electrocatalytic hydrogen evolution at unusu ...

2006

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 ...

The electroreduction of hydrogen on platinum(111) in acidic media

Nicola Marzari, Roberto Car

We propose a new mechanism for the electroreduction of hydrogen in acidic media. The specific model and theoretical calculations are designed for the Pt(111) surface, because this is the only face that exhibits a clear first order phase transition. The bas ...
