在这里，我们提出了一种简单的超声辅助方法来制造中空介孔硅球。所制备的中空介孔硅胶球具有尺寸调节好、比表面积大、介孔均匀等特点。随时间变化的实验结果表明，空心球的形成经历了一个选择性蚀刻过程。火毒性试验结果表明，空心介孔二氧化硅的掺入对环氧树脂燃烧分解的有毒气体有明显的抑制作用。
Here, we present a facile ultrasonic-assisted method to fabricate hollow mesoporous silica spheres. The prepared hollow mesoporous silica spheres own well-regulated size, large specific surface area, and homogeneous mesoporous. Time-dependent experimental results depict that the formation of the hollow spheres undergoes a selective etching process. The results of fire toxic tests show that the toxic gases decomposed from the combustion of epoxy resin were observably inhibited with the incorporation of hollow mesoporous silica.
