Synthesis and characterization of nano-structured porous granules, with fairly defined morphology and porosity, is crucial because such granules are widely utilized for various technological applications. However, an easy, one-step, economic synthesis protocol for large scale production is extremely desirable. In the present work, we have reported the synthesis and characterization of the nano-structured micro-granules using aerosol drying of bi-colloidal suspension of nano-silica and milk. Removal of soft organic component from the granules results in formation of meso and macro pores with moderate specific surface area. Granule morphology and porosity depends strongly on the concentration ratio of the individual components in the drying aerosol as well as the interaction between them.
合成并表征具有相当明确形态和孔隙率的纳米结构多孔颗粒至关重要，因为此类颗粒广泛应用于各种技术领域。然而，非常需要一种简便、一步法且经济的大规模生产合成方案。在本工作中，我们报道了利用纳米二氧化硅和牛奶的双胶体悬浮液进行气溶胶干燥来合成并表征纳米结构微颗粒。从颗粒中去除软有机成分会形成具有适度比表面积的介孔和大孔。颗粒形态和孔隙率在很大程度上取决于干燥气溶胶中各组分的浓度比以及它们之间的相互作用。
