Abstract
In this study, two particle sizes of mesoporous silicon dioxide spheres (sample A and B) were synthesized with didecytrimethylammonium bromide as template, and tetraethyl orthosilicate (TEOS) as the silica source. The particles of the samples were extraordinarily uniform and regular. The diameters of the spheres were 439 ± 5 and 485 ± 5 nm. The samples were stable up to 1000°C. The samples revealed only one stage of the weight loss, and the slightly endothermic weight loss was 7.3% for sample A and 9.1% for sample B. It showed that the prepared samples had the higher thermal stability.
