摘要：

This paper exhibits good example of high well-defined hollow silica spheres by using a low-cost sodium silicate precursor via a facile method. The N-2 adsorption isotherm shows that this hollow structure leads to a high Brunauer-Emmett-Teller specific area of ca. 217.755 m(2) g(-1). Transmission electron microscopy and scanning electron microscopy images indicate that prepared hollow silica spheres have uniform morphology and narrow size distribution. Particle size analyzer measurement (polydispersity = 0.005; GSD = 1.073) also further confirms the fact that hollow silica spheres with high monodispersity have been successfully developed as expected.
