以Zr（SO4）2. 4H2O和CH3COONa为原料，采用水热法制备了花状分级结构的硫酸氧化锆前驱体，前驱体经煅烧后可转变为氧化锆纳米结构，并保持了原始形貌。详细研究了硫酸锆和氧化锆纳米结构，并提出了可能的形成机制。在花状分级硫酸氧化锆的形成过程中，由CH3COONa控制pH在确定形貌中起着至关重要的作用。花状分级氧化锆对罗丹明B的光催化降解表现出良好的光催化活性。
Flower-like hierarchical zirconium oxide sulphate was prepared using Zr(SO4)2·4H2O and CH3COONa as raw materials via a hydrothermal process and the precursor could be transformed by calcination to zirconia nanostructures, maintaining the original morphology. The zirconium oxide sulphate and zirconia nanostructures were investigated in detail and possible formation mechanisms are proposed. In the formation of the flower-like hierarchical zirconium oxide sulphate, pH control by CH3COONa played a crucial role in determining the morphology. Flower-like hierarchical zirconia showed excellent photocatalytic activity for the photodegradation of Rhodamine B.
