Abstract
XRD have been used to study Pd/r-AI2O3 catalysts prepared by solution impregnation method. Effect of metal loading and calcination and reduction temperatures were studied to observe active metal particles growth. On calcination, growth of tetragonal PdO was observed only at 400 and 500°C. However, for hydrogen reduced catalysts, fine face centred cubic particles growth was observed even for 300°C treated catalysts. Catalysts with metal loading
