Effect Of Impregnation Procedure Of Pt/y-AL203 Catalysts Upon Catalytic Oxidation Of CO
ABSTRACT The oxidation of carbon monoxide by oxygen using two catalysts prepared by two different methods has been investigated. In the first method, catalyst prepared by immersing y-Al203 into the hexachloroplatinic acid solution at 80°C for 4 h, resulted Pt/y-Al203 catalyst having platinum highly...

| Summary: | ABSTRACT
The oxidation of carbon monoxide by oxygen using two catalysts prepared by two different methods has been investigated. In the first method, catalyst prepared by immersing y-Al203 into the hexachloroplatinic acid solution at 80°C for 4 h, resulted Pt/y-Al203 catalyst having platinum highly dispersed on the support. While that of immersing y-Al203 in the hexa-chloroplatinic acid solution at room temperature for 12 h, produced Pt/ y-A/203 catalyst where platinum dispersion was much lower. Catalytic activity test showed that platinum well dispersed on the support enhanced the activity for oxidation of carbon monoxide. The platinum impregnated at room temperature resulted in the poor activity.
