The Bi2Fe4O9 fibrous precursor is successfully synthesized through electrospinning technique, and the single-phase claviform Bi2Fe4O9 is obtained after calcining the precursor. The UV-vis absorption spectrum shows that the absorption range of the as-prepared Bi2Fe4O9 is wide, which indicates that the as-prepared Bi2Fe4O9 could be a photocatalyst with visible-light-driven photocatalytic activity. In addition,the result of magnetic hysteresis loop for Bi2Fe4O9 shows weak ferromagnetism and good soft magnetic properties, which indicate that the as-prepared Bi2Fe4O9 has a good application in soft magnetic material.
