| Abstract/Summary |
Mixed oxide-based catalysts prepared by the thermal decomposition of M(II)|Al hydrotalcite-like compounds (M(II) = Co, Cu, Ni, or Mg) were used in catalytic decomposition of nitrous oxide into nitrogen and oxygen. The prepared hydrotalcites as well as calcined products were characterized by the thermal analysis (TG/DTA), X-ray powder di raction, infrared spectroscopy, and BET surface area measurements. The catalytic reaction was performed in a xed-bed reactor at 1000 ppm N2O inlet concentration in the temperature range 330|450C, the space velocity was 60 000 cm3 g−1 h−1. Ni- and Co-containing catalysts showed high activity in nitrous oxide decomposition. A very poor activity for Mg—Al mixed oxide catalyst was observed.
