Thermogravimetric and differential scanning calorimetry, x-ray diffraction, atomic force microscopy, scanning electron microscopy and transmission electron microscope were used to characterize the reaction products. The results show that heating rate of copper tartrate has a significant effect on catalyst particle size and fiber morphology. Three different kinds of fiber morphologies can be obtained at the heating rate of 1-10 degrees C min(-1).
