Mesoporous silica SBA-15 was synthesized for controlled release applications of the natural antibacterial, allyl isothiocyanate (AITC). Two different molar ratios of silica were used as 1.00 (SBA-15a) and 0.74 (SBA-15b). This 26% reduction gave the same parallel-sided cylindrical pore shapes, but increased the mean pore width 38% and pore volume 37%. Adsorption of AITC from vapor phase resulted in...
The ordered, mesoporous silica structures MCM-41 and SBA-15 were synthesized as potential vectors for the controlled release of allyl isothiocyanate. The average pore diameter of each silica was 2.45 ± 0.25 nm and 7.28 ± 0.50 nm, however the average pore volume across both samples was 0.817 ± 0.010 mL/g. The maximum loading was 95.3% and 93.9%; the wider pore size of SBA-15 ensured 80% of the available...
