dc.description.abstract | The effect of pH during sol-gel synthesis on the structural and physicochemical properties of a Pd-Al2O3 three-way catalyst (TWC) prepared by the sol-gel method was investigated by using BET, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM) and solid state Al-27 MAS NMR. The Pd-Al2O3 catalyst prepared at pH=10 (Pd-Al2O3-B) showed a high activity in three-way catalytic reaction, a high dispersion of Pd, and Large surface area and pore volume. A basic condition (pH=10) in the sol-gel process was essential for the preparation of highly dispersed palladium clusters on alumina gel. The formation of highly stable palladium oxide species in Pd-Al2O3-B that were not completely reduced at 423 K was ascribed to the strong interaction between Pd and oxygen in alumina texture, resulting in the formation of -Al-O-Pd bond.
