%X A 0.4 wt%Pt/Ce 0.76Zr 0.19Zn 0.05O 1.95 catalyst was prepared by the evaporative drying method. The catalytic toluene oxidation activity of the catalyst was investigated and the calcination temperature dependence on the toluene oxidation activity was characterized. It was confirmed that only CO 2 and steam were produced by the complete oxidation of toluene, and no toluene-derived compounds were detected as by-products with a gas chromatography-mass spectrometer. Toluene was completely oxidized at 320 ˇăC on the 0.4 wt%Pt/Ce 0.76Zr 0.19Zn 0.05O 1.95 catalyst calcined at 500 ˇăC. The toluene oxidation activity slightly decreased with increasing the calcination temperature of the catalyst. However, significant deactivation was not recognized in the present 0.4 wt%Pt/Ce 0.76Zr 0.19Zn 0.05O 1.95 catalyst, and toluene was completely oxidized at 360 ˇăC even after calcination at 1000 ˇăC. From these results, it became obvious that the 0.4 wt%Pt/Ce 0.76Zr 0.19Zn 0.05O 1.95 catalyst has high thermal stability for toluene oxidation activity.
