The main results in the literature concerning the thermodynamics, the kinetics and the stoichiometry of adsorption of hydrogen in gas phase are compared to those obtained in liquid phase by transient electrochemical methods on platinum catalysts. Two

The influence of solution composition (nature of anions and cations, pH) in the aqueous phase catalytic hydrogenation of CC bonds (maleic acid) has been investigated. In weakly acidic solutions (of pH 3 and 6) the influence of the commonly used an

Platinized platinum catalysts were modified “in situ” by copper (sub)monolayers deposited under controlled conditions by electrochemical methods. They were characterized “in situ” by linear potential sweep cyclic voltammetry. Various Cuads/Pt

This study focused on the selective deposition of Au0 onto (111), (100) faces and (111)/(100) edges of cuboctahedral Pt particles present on the Pt/C(graphite) model system. The Pt–Au/C catalysts were prepared by novel surface redox methods involvi

The bimetallic catalysts Pt−Au/C (graphite) were prepared by selectively depositing Au on supported monometallic Pt/C catalysts by means of the reduction “in situ” of AuCl4-. The parent metal (Pt) ...

The hydrogenation reaction of maleic acid, catalyzed by platinized platinum, was investigated in the presence and in the absence of gaseous hydrogen, and with/without an external control of platinum potential, in different acid supporting electrolyte

The electrocatalytic hydrogenation of m-xylene (1,3-dimethylbenzene) was investigated at room temperature in 0.5 M H2SO4 solutions on a platinized-platinum (Pt/Pt) electrode. It was found that the hydrogenation process of m-xylene took place only in
