Electrospun LaAlO3 nanofibers from different solvent systems

Abstract

LaAlO₃ nanofibers are prepared using reproducible and green electrospinning technique. Particularly, N,N-dimethylformamide (DMF) and acetic acid/water (A-A/W) were used as solvents. The structural and textural properties were compared. Results indicate that the diameter of as-spun nanofibers with (A-A/W) ranged from 50 to 400 nm. While it is between 100 and 600 nm for (DMF). After calcination, it decreased to an average of 80 nm for (A-A/W) and 200 nm for (DMF). Higher pore volume (0.69 cc g⁻¹) and surface area (176.3 m² g⁻¹) were achieved for (A-A/W) solvent. The textural properties confirm that LaAlO₃ exhibit high performances for advanced technologies mainly sensors.
