Preparation of CeO2–ZrO2 ceramic fibers by electrospinning

Electrospinning was employed to fabricate polymer–ceramic composite fibers from solutions containing poly(vinyl pyrrolidone) (PVP), Ce(NO3)3⋅6H2O and ZrOCl2⋅8H2O. Upon firing the composite fibers at 1000 °C, Ce0.67Zr0.33O2 fibers with diameters ranging from 0.4 to 2 μm were synthesized. These fibers exhibit strong resistance to sintering. They still have specific surface area around 11.8 m2/g after being heated at 1000 °C for 6 h.

Figure shows that these Ce0.67Zr0.33O2 ceramic fibers calcined at 1000 °C are a mixture of dense and hollow fibers with a diameter of 0.4–2 μm.Figure optionsDownload as PowerPoint slide
