    摘要： The internal and external walls of the carbon nanotubes are doped with nano-sized metallic catalyst particles uniformly to a degree of 0.3-5 mg /cm2. The carbon nanotubes are grown over a carbon substrate using chemical vapor deposition or plasma enhanced chemical vapor deposition. Since the carbon nanotubes have a large specific surface area, and metallic catalyst particles are uniformly distributed over the internal and external walls thereof, the reaction efficiency in an electrode becomes maximal when the carbon nanotubes are used for the electrode of a fuel cell. The carbon nanotubes fabricated using the method can be applied to form a large electrode. The carbon nanotubes grown over the carbon substrate can be readily applied to an electrode of a fuel cell, providing economical advantages and simplifying the overall electrode manufacturing process. A fuel cell using as the carbon nanotubes for its electrode provides improved performance.

    摘要： An electrode catalyst for a fuel cell having comparable electrochemical activity as a platinum electrode catalyst but is much cheaper than the platinum electrode catalyst has a structure in which palladium and at least one metal catalyst selected from the group consisting of nickel, gold, iron, and silver, and combinations thereof, are supported on a tungsten carbide and carbon mesoporous composite support. A membrane electrode assembly and a fuel cell including the electrode catalyst also has comparable electrochemical activity as a platinum electrode catalyst but is also much cheaper than the platinum electrode catalyst.

    摘要： The present invention provides a simple method of mass producing high purity carbon nanocages. The method of preparing carbon nanocages comprises introducing an inert gas into a reactor equipped with a spray nozzle and raising the temperature of the reactor to a pyrolysis temperature of a catalyst compound. The method further comprises spraying a reactant including the catalyst compound and a carbon-containing compound into the reactor through the spray nozzle, wherein the ratio of a space velocity of the inert gas to a space velocity of the reactant is 100 or more.

    摘要： A method of preparing a supported catalyst includes dissolving a cation exchange polymer in alcohol to prepare a solution containing cation exchange polymer; mixing the cation exchange polymer containing solution with a catalytic metal precursor or a solution containing catalytic metal precursor; heating the mixture after adjusting its pH to a predetermined range; adding a reducing agent to the resultant and stirring the solution to reduce the catalytic metal precursor; mixing the resultant with a catalyst support; adding a precipitating agent to the resultant to form precipitates; and filtering and drying the precipitates. The method of preparing a supported catalyst can provide a highly dispersed supported catalyst containing catalytic metal particles with a reduced average size regardless of the type of catalyst support, which provides better catalytic activity than conventional catalysts at the same loading amount of catalytic metal.
