Abstract

The present work presents the results of direct catalytic decomposition of nitrous oxide over CuO and its Pr-, Sm- and Tb-promoted catalysts. These catalysts were prepared by the microwave assisted precipitation method, using oxalic acid as precipitant, and subsequent calcination at 500 °C. X-ray diffraction (XRD) was used for identification of the composition of the dried oxalate precursors and their calcination products. Thermogravimetric analysis (TGA) was used to follow up the thermal stability of the prepared precursors. The obtained catalysts were characterized by Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM), transmission electron microscopy, electrical conductivity and (TEM) H temperature programmed reduction (H-TPR). An enhancement effect of the added rare earth elements was observed during NO decomposition over the prepared catalysts Assessment of the de-NO activity was discussed based on the electrical conductivity as well as the H-TPR results.
