Abstract Lanthanum ferrite (LaFeO3) and Co-doped LaFeO3 nanofibers with perovskite-type structure had been synthesized via electrospinning. The structure and morphology of the nanofibers were characterized by various techniques. The as-prepared products combined the advantages of well crystallinity and the surface of samples was concave-convex and rough. In addition, the crystalline size of LaFeO3 decreased after Co doping. The gas-sensing properties of two samples were measured, Co-doped LaFeO3 presented good selectivity and high response toward acetic acid compared to pure LaFeO3 nanofibers. The results demonstrated that Co-doped LaFeO3 nanofibers could be used as a promising material for selective detection of acetic acid.
