The electrochemical activity of carbon-supported cobalt–palladium alloy electrocatalysts of various compositions have been investigated for the oxygen reduction reaction in a 5 cm 2 single cell polymer electrolyte membrane fuel cell. The polarizati

The oxygen reduction reaction (ORR) has been studied on platinum free, palladium-based electrocatalysts in acid media. Polycrystalline electrodes were prepared by electrodeposition on a polycrystalline gold substrate using a dual ligand approach at r

Mercury-mediated synthesis was shown to be a practical approach for preparing oxides of certain metals with the particle size in the nanoscale range. Growth of oxide monoliths of active metals such as Al, Sc and Y was achieved by dissolving the metal

The preparative-scale synthesis of intermetallic phases in the Al−Au and Al−Pd systems can be achieved at the relatively low temperature of boiling Hg (∼350 °C at 1 atm). In particular, Al2Au, AlAu, AlAu2, Al3Pd2, and AlPd can be made in high

In situ images of Ge(110) and Ge(111) surfaces under potential control have been obtained with an atomic force microscope (AFM) and a scanning tunneling microscope (STM). Atomic resolution images, using the AFM, of Ge(111) and Ge(110) revealed lattic

Surface X-ray scattering (SXS) and scanning tunneling microscope (STM) studies have been carried out to determine the structure of electrochemically deposited Bi monolayers on a Au(111) electrode. Between 10 and 190 mV (relative to bulk deposition),

The use of appropriately prepared silica gel and alumina has been found to mediate the addition of hydrogen halides to alkynes. The technique has been rendered even more convenient by the use of various organic and inorganic acid halides that react i
