Effect of pH in the preparation step on the reactivity of the thermal stability of Pd-Al2O3 sol-gel catalyst was investigated by using simulated reaction, BET, XRD, XPS and TEM. The Pd catalyst prepared in basic condition showed larger surface area, higher three-way catalytic activity and better thermal stability than one prepared in the acidic condition.
