The Influence of Different Preparation Methods on the Activity for CO Oxidation on the LDHs-supported Gold Catalysts
Au nanoparticles supported on MgAl-LDHs has been synthesized by coprecipitation method,gold colloid routs as well as intercalation and assembly method respectively.The influence of the above different preparation methods on the activity of the gold catalysts for CO oxidation was investigated,and the phase and gold particle size distribution of the catalysts were analyzed by XRD and TEM respectively.The results show that 100% conversion of CO on the fresh prepared gold catalysts synthesized by gold colloid routs and intercalation assembly method can be achieved at room temperature when the catalysts were activated at 473K for 2h in the air.The gold particle size distribution was range from 2nm to 7nm.
