Herein, CdO/ZnO core/shell nanofibers (NFs) were fabricated by one-pot electrospinning technique form a solution composed of poly(vinyl alcohol), zinc acetate dihydrate, and cadmium acetate dihydrate. CdO/ZnO core/shell NFs exhibits an excellent photo-degradation of methylene blue (MB) under sunlight irradiation compared to pristine ZnO NFs. As 98.4% and 42.4% of MB dye was de-colorized during 210 min using CdO/ZnO core/shell NFs and pristine ZnO NFs, respectively. The photo-degradation reaction of MB with CdO/ZnO core/shell NFs followed the pseudo-first-order relation.

一锅法制备CdO / ZnO核/壳纳米纤维:一种有效的光催化剂

在此,CdO / ZnO核/壳纳米纤维(NFs)是通过一锅静电纺丝技术制成的,该溶液由聚乙烯醇,醋酸锌二水合物和醋酸镉二水合物组成。与原始ZnO NFs相比,CdO / ZnO核/壳NFs在阳光照射下表现出优异的亚甲基蓝(MB)光降解性能。在210分钟内,分别使用CdO / ZnO核/壳NFs和原始ZnO NFs使98.4%和42.4%的MB染料脱色。MB与CdO / ZnO核/壳NFs的光降解反应遵循拟一阶关系。
