Abstract EN
Cobalt(II,III) oxide, Co3O4, is a promising catalyst for nitrous oxide direct decomposition.
In this paper we report effect of doping with some rare earth (RE) elements (Pr, Sm, and Tb) on the morphology and crystallite size of Co3O4 nanorods.
The various precursors (RE/Co oxalates) were prepared via the microwave assisted method and subsequent calcination.
The decomposition pathway of these precursors was followed using thermogravimetric analysis (TGA).
Based on thermal analysis results, Pr-, Sm-, and Tb-doped Co3O4 samples were obtained via the calcination in static air at 500°C for their oxalate precursors.
X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and hydrogen temperature programmed reduction (H2-TPR) were used to characterize the RE-doped cobalt oxide catalysts.
The activity of the prepared catalysts was investigated for N2O direct decomposition and compared with that of the undoped Co3O4 catalyst.
It was shown that the promoted Co3O4 catalysts revealed higher activity compared to the unpromoted one.
The dependence of the activity on both the catalysts particle size and the reduction behaviour was discussed.
