摘要：
We report the effective fabrication processes for more practical monolith catalysts consisting of washcoated alumina on a cordierite honeycomb monolith (CHM) and iron oxides nanoparticles in the alumina prepared by a simple dry coating method. It is confirmed that iron oxide nanoparticles were well deposited into the mesopore of washcoated alumina which is formed on the corner wall of honeycomb channel, and the effect of annealing temperature was evaluated for carbon monoxide oxidation catalysts. Fe2O3/gamma-Al2O3/CHM catalysts annealed at 350 degrees C exhibited the most enhanced catalytic activity, 100% conversion efficiency at more than 200 degrees C operating temperature.
