Catalytic decomposition of benzothiophenic and dibenzothiophenic sulfones over MgO-based catalysts

- Among various MgO based catalysts, MgO/SiO2 showed uniquely high activity and desired selectivity.
- Catalytic activity for sulfone decomposition was greatly influenced by crystallite size of MgO.
- MgO/TiO2 promoted undesired conversion of sulfones back to sulfur compounds.
