摘要

采用可重复的绿色电纺丝技术制备了 LaAlO3 纳米纤维。特别是使用了 N,N-二甲基甲酰胺（DMF）和醋酸/水（A-A/W）作为溶剂。对其结构和纹理特性进行了比较。结果表明，用（A-A/W）纺出的纳米纤维直径在 50 至 400 nm 之间。而（DMF）的直径在 100 到 600 nm 之间。煅烧后，（A-A/W）和（DMF）的平均直径分别减小到 80 nm 和 200 nm。(A-A/W) 溶剂的孔隙体积（0.69 cc g-1）和表面积（176.3 m2 g-1）更大。纹理特性证实，LaAlO3 在传感器等先进技术方面具有很高的性能。

Electrospun LaAlO3 nanofibers from different solvent systems

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.
