Sulfonic acid-functionalized mesoporous silica (SBA-Pr-SO3H) as solid acid catalyst in organic reactions

• An overview on the application of sulfonic acid functionalized SBA-15 was described.
• SBA-Pr-SO3H was proved to be a highly efficient solid acid catalyst.
• The role of SBA-Pr-SO3H in various organic reactions was described.

Mesoporous silica SBA-15 has been functionalized with sulfonic acid to create highly powerful heterogeneous solid acid catalysts (SBA-Pr-SO3H). The catalyst can be easily removed from the reaction mixture by simple filtration, recovered and reused without significant loss of activity. In this review, the catalytic activity of sulfonic acid-functionalized SBA-15 has been widely studied.
