<p>The particles of the Pt metal were well dispersed on carbon nanotubes when EG was used and in isopropanol poor dispersion was observed and no further investigation was done on them. The platinum wt% on the supports observed from EDS was 21.8, 19.10 and 16.74wt% for Pt/EMWCNT, Pt/LPGCNT and Pt/ commercial CNT respectively. Pt/LPGMWCNT showed high electro-catalytic activity of 2.48 mA and active surface area of 76 m2/g, toward oxygen reduction, observed from cyclic voltammogram in iv sulfuric acid. Pt/LPGMWCNT also showed better tolerance toward methanol, however it was not highly active towards methanol, and hence the methanol oxidation peak current observed between 0.75 and 08 potential was the smallest. In this study a wide range of instruments was used to characterize the properties and behavior of Platinum nanoparticles on multi-wall carbon nanotubes. To add to the already mentioned, Scanning electrochemical microscopy (SEM), proton induced x-ray emission (PIXE), scanning electrochemical microscopy (SECM) and Brunauer-Emmett Tellar (BET) were also used.</p>

A series of nickel(II) and Pt(II) complexes supported by the bis(2-diphenylphosphinophenyl)amide ligand, [PNP]¢w have been prepared. In Nickel(II) chemistry, the halide complexes are both air and water stable. The nickel(II) alkyl and aryl derivatives were presented including those in which the alkyl contains

The importance of platinum group metals for catalytic and microelectronic applications has prompted research into the development of novel molecular precursors for chemical vapor deposition of thin films of these metals. A variety of molecular architectures, ligand systems, as well as deposition conditions are investigated and related to the morphology and composition of the resultant films. For example, amorphous thin films of ruthenium and phosphorus alloys are deposited using single source metal hydride precursors, while use of the 3,5-di-substituted pyrazolate ligand in conjunction with various rhodium starting materials leads to a variety of different volatile monomeric and dimeric complexes. Synthesis of pyrazole and pyrazolate complexes of tungsten and palladium are also explored. In a related research area, progress towards the development of novel synthetic routes to mesostructured transition metal phosphides and borates for Li-ion battery electrode applications is summarized. Traditional routes to these materials involve high-temperature syntheses, allowing limited control over morphology. Identification of low-temperature reaction conditions necessary to afford a desired composition, morphology and electrochemical performance of the bulk material are the main goals of this project, and results are discussed with various early transition metals. / text
