Abstract
This paper presents a facile synthesis of nano-silica by hydrothermal treatment assisted by cetyltrimethylammonium bromide (CTAB). The effect of CTAB on the morphology of the material was also investigated. Structure, morphology, and composition of the material were studied byvarious methods such as XRD, SEM, FT-IR, and EDX.The results showed that a sample of nanosilica with amount of 1,0 g CTAB at pH 10-11 reached the most appropriate size, with the average length and width are 231,34±48,98 nm và 113,05±16,45 nm, respectively. In addition, the results indicated that the nanoparticles are completely pure, with many silanol groups on the surface, suitable for applications in bone tissue engineering and other biological applications.
