Comparative sonochemically synthesis of CeO2-doped Pd/clinoptilolite and Pd/Al2O3 nanocatalysts used in total oxidation of toluene at low temperatures for polluted air treatment

This research carried out using hybrid ultrasound impregnation method to synthesize supported Pd on binary CeO2 doped supports, clinoptilolite and Al2O3. Physiochemical properties of the catalysts such as XRD, FESEM, BET and FTIR were analyzed. The catalytic performance test carried out through oxidation of toluene under various temperatures and toluene concentrations. Among ceria doped supported catalysts, Pd/Al2O3-CeO2 had the best abatement performance and the reaction completion occurred at 250 °C. Pd/Al2O3-CeO2 also passed successful stability tests over more than 720 min time on stream.175
