以油菜花粉为生物模板, 通过温和易控的水浴-陈化法制备了纳/微米结构ZrO2 中空微球. 利用扫描电子显微镜(SEM)、红外光谱(FTIR)、X 射线能谱(EDS)、X 射线衍射(XRD)、比表面孔隙度分析、热分析等对所制备的产物和前驱体进行了表征, 并对产物的吸附性能进行了初步的研究. 结果表明, ZrO2 中空微球的球壳由纳米粒子构筑并形成介孔结构. 花粉模板前处理方式不同, 其模板作用不同, 可以获得两种不同球壳厚度、表面形貌和比表面积的ZrO2 中空微球. 其中“镂空”结构的ZrO2 微球对铬黑T 有良好的吸附性能. 对ZrO2 中空结构形成的机理进行了分析和讨论.

ZrO2 hollow microspheres, with thick shell and “network-wall”, were successfully synthesized by a facile and mild water-bath method using the rape pollen as a bio-template. The scanning electron microscope (SEM), X-ray diffraction (XRD), FT-IR, N2 adsorption-desorption analyses and thermal analysis were used for the structural characterizations of the products and the precursors. The adsorption performance of products was researched preliminarily. The results show that the shell of ZrO2 hollow microspheres consists of the nanoparticles to cause the formation of the mesoporous structure. Two kinds of ZrO2 hollow microspheres with different shell thickness and surface morphology can be achieved when the ways for treatment pollen is different. The “network-wall” ZrO2 hollow microspheres have a unique morphological, higher surface area and stronger adsorption capability for eriochrome black T. We also discussed the formation mechanism of the ZrO2 hollow microspheres by inducing of pollen.
