METHOD FOR SYNTHESISING MICROPARTICLES |
摘要 |
A method for synthesising mesoporous silica microparticles comprising the steps of: —preparing a sol from an ammonium catalysed hydrolysis and condensation reaction of a pre-sol solution comprising a silica precursor and a structure directing agent dissolved in a mixed solvent system comprising an alcohol and water to produce mesoporous particles of silica with an average diameter of up to about 50 μm; hydrothermally treating the particles to increase the pore size; treating the particles to remove residual structure directing agent; and further increasing the pore size using controlled dissolution.
