摘要：
A well known method was used to convert the solid silica spheres to porous silicon spheres with high surface area, with the starting shape retained. The presented work demonstrated that the porous silicon spheres are composed of polycrystal morphology. Due to the quantum confinement effect, the photoluminescence emission centered at 621 nm. The results of N-2 adsorption and desorption analysis indicates the mesoporous silicon spheres possess a surface area around 88 m(2) g(-1) and single point micro-pore volume 0.173 cm(3) g(-1).
