PRODUCTION METHOD FOR A CARBON-BASED COMPOSITE METAL OXIDE NANOCATALYST CARRIER, AND COMPOSITE METAL OXIDE NANOCATALYST CARRIER THEREFROM

摘要

The present invention relates to a production method for a carbon-based composite metal oxide nanocatalyst carrier and to a composite metal oxide nanocatalyst carrier therefrom, and more particularly relates to a technique wherein a melt impregnation process and a calcining process are used in order to ensure that active metal catalyst particles are uniformly carried at high density on an oxide metal used for a support and on a residual carbon support, and that agglutination between particles is prevented and hence high activity and stability are exhibited during high-temperature catalytic reactions. The present invention features a production method for a carbon-based composite metal oxide nanocatalyst carrier, the method comprising: a) a step (S100) of forming a mixed powder by mixing a hydrated metal oxide salt used for a catalyst, a hydrated metal oxide salt used for a support and a porous carbon template; b) a step (S200) of then carrying out melt impregnation at close to the melting points of the mixed hydrated metal oxide salts and so carrying out melt impregnation of the hydrated metal oxide salt used for an active catalyst and the hydrated metal oxide salt used for a support into the porous carbon template; a step (S300) of drying the melt impregnated mixed powder at room temperature; and a step (S400) of subjecting the dried mixed powder to high-temperature calcining so as to eliminate the carbon template and break down the hydrated metal oxide salt used for an active catalyst and the hydrated metal oxide salt used for a support and hence cause active metal oxide particles to be carried on a metal oxide used for a support and residual carbon, and the invention also features the carbon-based composite metal oxide nanocatalyst carrier produced thereby.
