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-AI,0, into the hexachloroplatinic acid solution at 80°C for 4 h, resulted Ptly-Al20, catalyst having platinum highly dispersed on the support. While that of immersing y-A/20, in the hexa-chloroplatinic acid solution at room temperature for 12 h, produced Pt/y-A1,03cata/yst where platinum dispersion was much lower. Catalytic activity test showed that platinum well dispersed on the support enhanced the activity of oxidation of carbon monoxide. The platinum impregnated at room temperature resulted in the pooractivity. Keyword: Catalyst, CO Oxidation, Platinum.
