Supported catalyst comprising nano-metal catalyst supported on carbon nanotubes directly grown on surface of the catalyst support and method of preparing the supported catalyst

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 son 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.
