Abstract:
Currently, there is a great amount of ongoing research involved in catalytic converters because of their interesting applications in eliminating toxic gases from exhaust pipes. Many types of porous materials have been widely studied and used to increase the catalytic activity. In this work, mesoporous ceria-zirconia (CeO₂-ZrO₂) was synthesized using MCM-48 as a hard template via the nanocasting method. The obtained product provided a high surface area of 248.5 m²/g. The optimum conditions were to stir for 4 h at h 100 ℃ evaporation Temperature of solvent. The synthesized mesoporous CeO₂-ZrO₂ was characterized using X-ray diffraction (XRD), X-ray fluorescence (XRF), Transmission electron microscopy (TEM), And N₂ adsorption/desorption. The Temperature-programmed reduction results provided only Surface reduction temperatures at 280-620 ℃.
