Synthesis of unique mesoporous ZrO2-carbon fiber from collagen fiber

Hierarchical mesoporous ZrO2-carbon fiber was successfully synthesized by using collagen fiber as a structure-directing agent, and characterized by scanning electron microscopy, X-ray photoelectron spectroscopy and X-ray diffraction. The ZrO2-carbon fiber obtained is approximately 1-4 mu m in outer diameter and 0.5-1 mm in length, and the surface of the fiber exhibits ordered com-cob-like mesoporous morphology.
