The Pt-H atom interaction plays a key role in electrochemistry, particularly at the Pt/aqueous solution interface in the range of the potentials related to the H-adatom electrosorption equilibrium and hydrogen evolution reaction. The situation outlined above suggested the convenience of attempting a quantum chemistry approach to surface species that are likely formed at a simulated platinum/aqueous electrochemical interface in order to discriminate the structure and energy of possible H-adsorbates. This is a relevant issue in dealing with, for instance, the interpretation of the complex electrosorption spectra of H-atoms on platinum in an aqueous solution, as well as to provide a more realistic approach to the nature of H-atom intermediates involved in the hydrogen evolution reaction. 

In a sense, the aqueous chemistry of the platinum amines with respect to biological relevance may be divided into activation, deactivation and... 

The apparent rationale for study of the metallocene dihalides was that the cis geometry, Figure 6.4, was reminiscent of that of cisplatin, with a c chloride separation of 3.470 A for Ti, for example, in contrast to that in cisplatin, 3.349 A [102]. However, it is clear from studies of the hydrolysis of the cyclopentadienyl complexes that the aqueous chemistry is very different from that of platinum and no structural analogies should be drawn. In general, the complexes inhibit Ehrlich ascites tumours and solid growths of this tumour, are active in Lewis Lung, but are only very... 

When an electrolytic cell is designed, care must be taken in the selection of the cell components. For example, consider what happens when an aqueous solution of sodium chloride is electrolyzed using platinum electrodes. Platinum is used for passive electrodes, because this metal is resistant to oxidation and does not participate in the redox chemistry of the cell. There are three major species in the solution H2 O, Na, and Cl. Chloride ions...

Protonation and Reductive Elimination Reaction of a (Diimine)platinum (II) Dimethyl Complex It has been realized for some time that direct, selective methods for catalytic conversion of hydrocarbons to products of further value are important goals for chemistry investigators. This topic is notably complex and may be reviewed for the considerable body of research conducted heretofore.348-350 Aqueous...
