Abstract

The activities and durability of the oxidation of CO at ambient temperature and humidity on nanometer Au/NiO prepared by using different methods were studied, It was found that the activities and durability ofthe catalysts were greatly changed with the preparation methods and calcining temperature, Active and durable catalyst can be obtained by careful control of the preparation procedures. Among the samples tested, Au/NiO prepared by the following conditions-Na2CO3 solution was added into an aqueous solution of Ni(NO3)(2), HAuCl4 and dodecylbenzene sulfonic acid sodium salt (DBS), the resultant precipitate was heated to70 degrees C and washed with deionized hot water of 70 degrees C, followed by drying at room temperature for 48 h, and then the precipitatewas calcined at 300 degrees C-showed the highest activity and durability, it was even able to oxidize CO completely at 20 degrees C in the presence of 1.8% water vapor for 27 h.
