Mesoporous silica SBA-15 functionalized with used as a new recyclable nanocatalyst for the solvent-free conditions. The catalyst exhibited catalytic activity. 8-hydroxyquinoline-5-sulfonic acid (HQS-SBA-15) was one-pot synthesis of 2-thiohydantoin derivatives under excellent recyclability at least for 3 times with a high catalytic activity.
