The Pt/CeO2 nanofibers with diameter of 80-120 nm were prepared by electrospinning method with Ce(NO3)(3)center dot 6H(2)O as raw material and PVP as spinnable additive. This method included the preparation of spinnable sol and electrospinning process. After calcination at 400 degrees C, the fluorite structure Pt/CeO2 nanofibers with loose structure were obtained, which were composed of 5-10 nm particles. In the water-gas shift reaction, 1 wt.% Pt doped CeO2 nanofibers exhibited superior catalytic activity compared with pure CeO2 nanofiber, Pt loaded CeO2 powder and Pt loaded CeO2 nanofiber, and the CO conversion reaches 98% at 320 degrees C and maintains that until 360 degrees C, showing potential application in water-gas shift reaction.
