    摘要: The present invention is related to a high loading supported carbon catalyst having Pt or a Pt alloy supported into an electrically conductive carbon support. Specifically, in the carbon supported catalyst, a loading of the supported Pt or Pt alloy is in the range of about 50% to about 60% by weight, an average particle size is about 1 nm to about 3 nm, and a total specific surface area of the carbon supported catalyst is greater than about 200 m2/g. The carbon supported catalyst may improve the performance of a fuel cell because the catalytic metal particles have a small size and a high degree of dispersion. Also, a carbon supported catalyst having very fine catalyst particles uniformly dispersed may be prepared even at a high loading may be prepared.

    摘要: A catalyst for purifying exhaust gases of an automobile engine including a carrier coprecipitated with a material absorbing oxides of nitrogen (NO.sub.x) and an active noble metal wherein the material absorbing oxides of nitrogen is at least one of barium manganese oxide (BaMnO.sub.3) and calcium manganese oxide (CaMnO.sub.3). The carrier coprecipitated with BaMnO.sub.3 or CaMnO.sub.3 shows superior capacity for absorbing oxides of nitrogen. Consequently, a catalyst according to the present invention can effectively purify engine exhaust, even in a lean burn environment.

    摘要: An electrode catalyst for a fuel cell includes a complex support including at least one metal oxide and carbon-based material; and a palladium (Pd)-based catalyst supported by the complex support. A method of manufacturing the electrode catalyst includes dissolving a precursor of a palladium (Pd)-based catalyst in a solvent and preparing a mixture solution for a catalyst; adding a complex support including at least one metal oxide and a carbon-based material to the mixture solution for a catalyst and stirring the mixture solution to which the complex support is added; drying the mixture solution for a catalyst, to which the complex support is added, in order to disperse the precursor of the Pd-based catalyst on the complex support; and reducing the precursor of the Pd-based catalyst dispersed on the complex support. A fuel cell includes the electrode catalyst.
