溶剂热法制备ZnOHF微/纳米晶：锌源的影响
|
Abstract:
采用ZnSO4？7H2O，Zn(NO3)2？6H2O，Zn(OAc)2和ZnCl2作为Zn2+源，通过DMF辅助溶剂热法，制备了具有不同的形貌的(蛋挞状、海星状、盘、线) ZnO和ZnOHF。在紫外光照射下，研究了不同产物对罗丹明B溶液的光催化性质，发现RhB的降解率遵循如下顺序：蛋挞状ZnO > ZnO纳米盘 > ZnOHF纳米线 > 海星状ZnOHF，表明了罗丹明B的降解效率与产物的形貌之间存在明确的构效关系。
ZnSO4？7H2O, Zn(NO3)2？6H2O, Zn(OAc)2 and ZnCl2 were adopted as Zn2+ sources to synthesize ZnO or ZnOHF with different morphologies (hierarchical cake-like microstructures, starfish-like microstructures, nanodisks, and nanowires) via a simple DMF-assisted solvothermal route. The photocatalytic properties of the products were investigated by the degradation of RhB aqueous solution under UV-light irradiation. The degradation efficiency for different morphological ZnO and ZnOHF follow the order of hierarchical cake-like ZnO ZnO nanodisks ZnOHF nanowires starfish-like ZnOHF, indicating strong shape-dependent photocatalysis behaviors.
