Sammanfattning

The effect of calcination and reduction temperature on the physical properties of PdZn/Al2O3 catalysts, prepared by co-precipitation deposition technique and characterized by XPS, XRD, and TEM methods are reported. The temperatures were varied in a range of 300-500°C. The catalyst calcined at 300°C and reduced at 400°C exhibited the metal particle size of 2-6 nm and contained the highest surface concentrations of Pd and Zn according to XPS measurements. The size and the fraction of large particles (above 10 nm) increased with increasing the calcinations and reduction temperatures.
