英文摘要：

La2Co Fe O6 bamboo-like hollow nanofibers photocatalytic material was successfully prepared by electrostatic spinning. La2 Co Fe O6 nanofibers, which were connected to each other by rhombic La2 Co Fe O6 nanoparticles, had stable one-dimensional structure and clear bamboo-like hollow structure. The specific surface area of as-prepared inorganic nanofibers reached 98.7 m^2/g. La2 Co Fe O6 nanofibers had a high utilization for natural light and its band gap was 1.6 e V. When concentration of methyl orange was 10 mg/L with p H of 2 and the dosage of La2 Co Fe O6 nanofibers was 1.5 g/L, methyl orange was degraded by La2 Co Fe O6 nanofibers within 2 h under natural light at 96.9%.
