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 ...
This paper is concerned with reaction systems in which fuel production is achieved by illumination of aqueous solutions. Research interest in this field focuses on the photoredox reaction A + D [graphic omitted] A–+ D+ in which A and D are solutes of which ...
Sodium salts such as Na2CO3 and Na molybdate are active and selective MeOH dehydrogenation catalysts for the prodn. of water-free HCHO. Profound chem. and structural changes are experienced by the molybdate when employed under normal reaction conditions (5 ...
A method for the simultaneous production of hydrogen and oxygen from water by the visible light irradiation of a water solution containing photosensitizer, an electron relay and a suitable combination of redox catalysts. ...

Dehydrohalogenation of haloaromatics in ionic liquids derived from ethylmethylimidazolium or similar salts has been performed using Pd-C, Pd(OAc)2 and other catalysts using formate salts as a hydrogen source. In the ionic liquid [emim][BF4< ...
Ruthenium(II)-arene diphosphine complexes are shown to be effective precursors for the catalytic hydrogenation of the C=C bond in an aqueous biphase using molecular hydrogen as the hydrogen source. A mechanistic study performed in water, utilizing high gas ...
NOVELTY - A 2-butene-1,4-diol is prepared by hydrogenating 2-butyne-1,4-diol in the presence of a structured catalyst and in the absence of a solvent. USE - For preparing 2-butene-2,4-diol that is an important industrial intermediate in the preparation of ...
A linear water-sol. quaternary ammonium polymer having a homopolymeric chain of repeating unit I (R1 and R2 = linear or branched alkyl, hydroxyalkyl, alkoxyalkyl groups having 1-6 C atoms; X- = anion and n = 30-220) was prepd. The polymer has a molar mass ...
