Catalytic wet peroxidation of pyridine bearing wastewater by cerium supported SBA-15

► Cerium supported SBA-15 (Ce/SBA-15) synthesized by two-step synthesis. ► Characterization of Ce/SBA-15 by FTIR, XRD and BET surface area. ► Catalytic peroxidation of pyridine by Ce/SBA-15. ► Optimization of parameters like catalyst dose, H2O2 dose, initial concentration and temperature. ► Catalyst reusability and leaching study performed.
