摘要:
以CTAB/环已烷/正己醇/乙酸锌水溶液组成的四元微乳液作为反应体系,采用水热微乳液法制备出由纳米片组成的花形微球ZnO产物,并用XRD、SEM、UV-vis对其进行表征,结果表明:所制备3D花形微球ZnO的结构为六方纤维矿,花形微球的直径为5μm,微球表面呈孔状结构,比表面积为16.5m2·g-1.以降解罗丹明B为模型降解物,研究了花形ZnO纳米微球和商用ZnO纳米颗粒的光催化活性.结果表明,与商用ZnO纳米颗粒相比,水热微乳液法所制备的花形ZnO微球具有更高的光催化活性,其原因可能与其较高的比表面积和
Abstract:
ZnO with flower·like microspheresstructures assembledby nanosheetswasprepared via the hydrothermal microemulsion route using CTAB／cyclohexane／n-hexanol／zinc acetate dehydrate as raw materials．The hierarchical ZnO microarchitecturewascharacterized by XRD，SEM and UV·vis．The results indicate that the product belongs to hexagonal ZnOwith wurtzite structure，and thediameter ofZnOmicrospheres is about5 Ixm．ZnO microspheres exhibit pore structures with high surface area of 16．5 m2·g～．The hierarchicalZnO microspheres exhibit higherphotocatalytic activity for decolorization ofRhodamineB underultraviolet irradiation than that ofcommercialZnOnanoparticles，which can be attributed to the larger surfaceareaand the spe— cial 3D structural feature of the nanosheets．
