| Abstract: | Hollow silica microspheres were prepared by using octylamine as templating agent and TEOS as silica source in acid condition.The prepared samples were characterized by SEM,XRD,N2 adsorption,IR,TG and DTA techniques.The results show that the synthesized hollow silica microspheres have smooth surface and dispersed well.There are bimodal nanopores in the hollow silica microspheres,with a diameter of 2.1nm and 0.62nm for the mesopores and micropores,respectively,giving a specific surface area of 1123m2/g and a pore volume of 0.6291mL/g. |
