Synthesis of silica hollow spheres assisted by ultrasound

A facile process for generating monolithic-structured nano-silica/polystyrene multi-core/shell microspheres by a seeded sol–gel process method

“…4b. In the case of the seed particles including TMSPM content of 5%, the significant weight loss was observed near 450°C similarly to PS particles [29]. The residual mass of 7-8 wt.% was found from the curve, which agreed with the weight proportion of inorganic parts in the seed.…”

Preparation of silica mesoporous nanoparticles functionalized with β-cyclodextrin and its application for methylene blue removal

“…A certain amount of CTAB was solved by stirring into 100 mL de-ionized water and sonication by prob sonicator for 2 min [31]. Then 2 mL NH 3 solution and 1 mL TEOS were added dropwise to the solution.…”

A facile method for the fabrication of vinyl functionalized hollow silica spheres

“…In recent years, many research groups [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] have reported the fabrication of hollow silica spheres with various particle sizes. Usually, organic or inorganic templates are employed in the processes for preparing hollow silica spheres.…”
