Abstract

Flake shaped ZnFe2O4 nanoparticles have successfully been prepared by co-precipitation method. The phase and crystallinity of the synthesised ZnFe2O4 nanoparticles were studied by XRD. The SEM result reveals that the flake shaped entities are formed by the combination of rod-shaped nanomaterial. The band gap of the synthesised ZnFe2O4 nanoparticles is found to be ∼ 2.14 eV by UV-Vis DRS measurements indicating thereby that this material absorbs visible light (λmax = 579.37 nm). The ferrite nanoparticles were successfully employed as a photocatalytic materials for the degradation of the dye Malachite green (MG) in aqueous medium with ∼ 99% efficiency under visible light irradiation.

片状纳米ZnFe2O4:合成、表征及可见光诱导光催化研究

采用共沉淀法成功制备了片状ZnFe2O4纳米颗粒。采用XRD对合成的纳米ZnFe2O4的物相和结晶度进行了研究。SEM结果表明，片状实体是由棒状纳米材料结合形成的。通过UV-Vis DRS测量发现，合成的ZnFe2O4纳米粒子的带隙为~ 2.14 eV，表明该材料吸收可见光(λmax = 579.37 nm)。在可见光照射下，铁酸盐纳米颗粒作为光催化材料在水介质中降解孔雀石绿(MG)染料，效率为99%。
