Abstract
Official abstract text for this publication.
The preparation of bimetallic gold-silver cerium dioxide-supported catalysts and the process of oxidation of carbon monoxide (CO) in air to remove CO using the gold-silver cerium dioxide-supported catalysts are disclosed. The gold loading is between 0.5 and 5 wt. %. Gold and silver particle sizes are between 1 and 3 nm, and Au/Ag weight ratio is between 1 and 10. Oxidation of CO in air over these catalysts is carried out in a fixed bed reactor to remove CO.
First claim
Opening claim text (preview).
What is claimed is: 1. A preparation method of nano-gold-silver cerium dioxide-supported catalysts, comprising the steps of: preparing gold-silver cerium dioxide-supported catalysts by a deposition-precipitation method, wherein gold/silver weight ratio is between 1 and 10, the gold loading is between 0.5 and 5 wt. %, and the preparation method is characterized in: mixing a silver nitrate solution and cerium dioxide (CeO 2 ) by a deposition-precipitation method; stirring the mixt…
