| Abstract: | Ultrafine SnO 2 and the SnO 2 supported Pd catalyst (Pd/SnO 2) are prepared by sol gel supercritical fluid drying method. An investigation is carried out on the activity and stability of the catalyst and the effect of calcination reduction conditions. The results show that the ultrafine SnO 2 supported Pd catalyst has a higher activity for catalytic oxidation than common SnO 2.The optimal calcination and reduction temperatures are 600℃ and 50℃, respectively. |
