摘要： A mesoporous carbon is prepared by mixing a carbon precursor, an acid, and a solvent to obtain a carbon precursor mixture; impregnating an ordered mesoporous silica (OMS) with the carbon precursor mixture; carbonizing the impregnated OMS at 800 to 1300° C. by irradiating microwave energy with a power of 100 to 2000 W thereon to form an OMS-carbon composite; and removing the mesoporous silica from the OMS-carbon composite.

摘要： The present invention is related to a short carbon nanotube for a catalyst support. In particular, the short carbon nanotube may be opened at both ends, a length of less than about 300 nm, and an aspect ratio in the range of about 1 to about 15. The short carbon nanotube has a broad surface area and better electric conductivity and is opened at both ends, thereby impregnating a metallic catalyst into the inner side of the carbon nanotube. Also, a catalyst impregnated carbon nanotube has a broad effective specific surface area, and thus, has an improved efficiency of catalyst utilization, can reduce an amount of the catalyst used and can efficiently diffuse a fuel. Accordingly, when catalyst impregnated carbon nanotube is used in a fuel cell, etc., improvements can be made in the pricing, power density of an electrode, and energy density of a fuel cell.

摘要： A method of preparing a supported catalyst, the method comprising mixing a first catalytic metal precursor and a first solvent to obtain a first catalytic metal precursor mixture; mixing a carbon support for catalyst and the first catalytic metal precursor mixture, and drying the mixture to obtain a primary supported catalyst precursor; subjecting the primary supported catalyst precursor to a hydrogen reduction heat treatment, to obtain a primary supported catalyst; mixing the primary supported catalyst and a polyhydric alcohol to obtain a primary supported catalyst mixture; mixing a second catalytic metal precursor and a second solvent to obtain a second catalytic metal precursor mixture; mixing the primary supported catalyst mixture and the second catalytic metal precursor mixture to obtain a secondary supported catalyst precursor mixture; and adjusting the pH of the secondary supported catalyst precursor mixture, and then heating the secondary supported catalyst precursor mixture to obtain a supported catalyst, a supported catalyst prepared by the method, an electrode comprising the supported catalyst, and a fuel cell including the electrode are provided. A supported catalyst having a desired amount of loaded catalytic metal particles can be obtained by preparing a primary supported catalyst containing catalytic metal particles that are obtained by a primary gas phase reduction reaction of a portion of the final loading amount of catalytic metal, and reducing the remaining portion of the catalytic metal by a secondary liquid phase reduction reaction. The supported catalyst contains catalytic metal particles having a very small average particle size, which are uniformly distributed on a carbon support at a high concentration, and thus exhibits maximal catalyst activity. A fuel cell produced using the supported catalyst has improved efficiency.

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.
