摘要
The rational design and precise synthesis of multifunctional hybrid nanostructures with a tailored active core and a large, dendritic, modified mesoporous structured shell can promote catalysis, energy storage, and biological applications. Here, an oil-water biphase stratification coating strategy has been developed to prepare monodisperse magnetic dendritic mesoporous silica core-shell structured nano- spheres. These sophisticated Fe3O4@SiO2@dendritic-mSiO2 nanospheres feature large dendritic open pores （2.7 and 10.3 nm）. Significantly, the silica shells can be converted into dendritic mesoporous aluminosilicate frameworks with unchanged porosity, a Si/Al molar ratio of 14, and remarkably strong acidic sites, through a post-synthesis approach. In addition, the resultant magnetic dendritic mesoporous aluminosilicate nanospheres exhibit outstanding properties and promising application in phosphate removal from wastewater.
合理设计和有一个定制的活跃核心和大、树枝状的、修改 mesoporous 的多功能的混合 nanostructures 的精确合成组织了壳能支持催化作用，精力存储，和生物应用。这里，油水双相层化涂层策略被开发了准备 monodisperse 磁性的树枝状的 mesoporous 硅石核心壳结构化的 nanospheres。这些复杂 Fe <sub>3</sub > O <sub>4</sub>@SiO<sub>2</sub>@dendritic-mSiO<sub>2</sub> nanospheres 特征大树枝状的开的毛孔(2.7 和 10.3 nm ) 。显著地，硅石壳能与未改变的孔， 14 的 Si/Al 臼齿的比率，和显著地强壮的酸的地点被变换成树枝状的 mesoporous 铝矽酸盐框架，通过一条合成以后的途径。另外，结果的磁性的树枝状的 mesoporous 铝矽酸盐 nanospheres 展览在从废水的磷酸盐移动的突出的性质和有希望的申请。
