Abstract
This paper exhibits good example of high welldefined hollow silica spheres by using a lowcost sodium silicate precursor via a facile method The N2 adsorption isotherm shows that this hollow structure leads to a high Brunauer–Emmett–Teller specific area of ca 217755 m2 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 = 0005 GSD = 1073 also further confirms the fact that hollow silica spheres with high monodispersity have been successfully developed as expected
