  • Method for synthesising microparticles
    Patent number: 11772978
    Abstract: A method for synthesizing mesoporous silica microparticles comprising the steps of: preparing a sol from an ammonium catalyzed 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 ?m; 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.
    Type: Grant
