JCPDS ﬁle 87-0639 of Pd has been used. Average crys-tallite size corresponding to the various crystal planes of Pd nanoparticles differs from 6.5 to 11.5 nm. It is clear from the plot that the average crystallite sizes pertaining to (111)
peaks of Pd and Ni (JCPDS file No. 05-0681 and JCPDS file No. 04-0850) of higher angles were closed to each other and their intensities were also very low. Results of the XRD analyses clearly
