摘　　要：本文以NH4BF4为氟源,在N,N-二甲基甲酰胺(DMF)辅助下,合成了不同形貌的ZnOHF微/纳米结构(纳米棒、微米管和纳米片),其中DMF既是溶剂,也是配体调节产物结构。本论文探究了DMF和H2O的比例在合成不同形貌的ZnOHF微/纳米结构过程中的作用。在紫外灯辐照下,测定了不同形貌的ZnOHF对罗丹明B溶液的光催化活性,结果表明在12.5 mL DMF/12.5mL H2O溶剂中,得到的微米管状ZnOHF的光催化性质最好。Employing NH4BF4 as fluoride, different morphological ZnOHF micro/nanostructures (nanorods, microtubes and nanosheets) have been synthesized with the aid of N,N-dimethylformamide (DMF). DMF is used both as solvent and structures functional agent in tuning the crystal phase and morphologies of the products. The ratio of DMF/H2O plays important roles in the formation of different morphological products. Under the irradiation of Uv-light, the photocatalytic activities of different morphological ZnOHF micro/nanostructures are investigated by the degradation of Rhodamine B solution. Resultantly, the ZnOHF microtubes exhibited the best photocatalytic properties which were synthesized in the presence of 12.5 mL DMF/12.5mL H2O.
