    摘要: Disclosed are a porous catalyst support for maximizing an increase in catalytic reaction activity and a method of preparing a nano-metal-supported catalyst using the same. The method includes splitting cellulose fibers, thus preparing a catalyst support, growing carbon nanotubes on the prepared catalyst support, and supporting a nano-metal catalyst on the catalyst support having the carbon nanotubes grown thereon. A nano-metal-supported catalyst including the cellulose catalyst support and the use of cellulose fibers as the catalyst support for supporting the nano-metal catalyst are also provided. When porous cellulose fibers having a plurality of micropores are used as material for the catalyst support for supporting a nano-metal catalyst, the preparation cost of the catalyst is reduced and the increase in catalytic reaction activity is maximized even with the use of a small amount thereof in various catalytic reactions. A technique for directly growing carbon nanotubes is applied, thereby controlling the electrical conductivity of the catalyst and increasing the surface area, and further, an expensive nano-metal catalyst component can be easily collected after the reaction, resulting in eco-friendly properties.

    摘要: Disclosed is a novel cellulose electrode having high performance, which is capable of substituting for carbon paper used as a conventional fuel cell electrode. A method of manufacturing the cellulose electrode includes cutting cellulose fibers to a predetermined length and binding the fibers, or directly weaving the fibers, thus producing a cellulose sheet, directly growing carbon nanotubes on the cellulose sheet, and supporting a platinum nano-catalyst on the surface of the carbon nanotubes using chemical vapor deposition. An electrode including the cellulose fibers and use of cellulose fibers as fuel cell electrodes are also provided. As a novel functional material for fuel cell electrodes, porous cellulose fibers having micropores are used, thereby reducing electrode manufacturing costs and improving electrode performance.
