Sonochemically Dispersion of Mn-Cu over Activated Clinoptilolite Used in Total Oxidation of Toluene at Low Temperatures: Effect of Impregnation Sequence

Mn-Cu nanocatalysts on modified clinoptilolite with different sequence were successfully prepared by ultrasoundirradiation to be utilized in catalyst oxidation of toluene at low temperature. The synthesized nanocatalysts werecharacterized using XRD, FESEM, EDX techniques. XRD patterns confirmed the formation of crystalline copper oxide.FESEM images showed high dispersion of active phase with size distribution nano-range on support. EDX analyses alsoshowed that good dispersion of active phase on support. Results of toluene oxidation indicated that synthesizednanocatalysts were highly active and stable to remove nearly 96% of toluene. The presence of nano size particles alongwith good characteristics of synthesized nanocatalysts presented them as highly efficient materials for toluene catalyticoxidation.
