Abstract EN
In this work, we report an efficient method to produce pure hollow silica spheres (HSS) using phenyltrimethoxysilane (PTMS) compound.
The production of HSS was carried out via hydrolysis of PTMS in the aqueous media and followed by a condensation reaction to form silica spheres with phenyl groups.
The product was then calcined to remove phenyl groups and obtain pure silica spheres with >95% fine structure.
The chemical nature of pure silica was confirmed by Fourier transforms infrared spectroscopy.
The calcined HSS were stable beyond the temperature of 900 C as confirmed by thermal gravimetric analysis (TGA).
The calcined spheres preserved their spherical appearance and hollow core as shown by SEM and TEM micrographs.
Interestingly, the average size of the spheres was reduced significantly after calcination from 760 to 510 nm, confirming further the removal of phenyl groups.
The calcined HSS offered much higher surface area (As) when analysed by BET; As for calcined product was 406 and mere 4.8 m2 /g for uncalcined HSS.
Finally, drug release study of cisplatin/HSS showed over 45% of steady cumulative release for 72 h.
The prepared HSS can be dispersed in water opening the possibility of many novel bio/non-bio applications
