Waste Gas

The catalytic oxidation of NOx from waste gas was investigated using advanced oxidation process based on sulfate radicals. The manganese oxide immobilized on graphene oxide (GO) can activate peroxymonosulfate (PMS) for the oxidation of NOx in water. The Mn3O4/GO catalyst system exhibited efficient activity for NOx oxidation when the Mn3O4/GO catalyst loaded an optimum Mn3O4. In addition, 52.28% oxidation could be achieved within 60 min with 0.25 mM catalyst, and 2 mM PMS. Therefore, the results may have significant technical implication for utilizing Mn2+/PMS to oxidize NOx for offgas treatment.
