Abstract:
Palladium nanoparticles have been grown on solid substrates (glass slide and ITO) using seed
mediated growth method with a various ratios of CTAB and PVP, and a various duration times of
growth. The particles were grown at 28-30’C. Characterizations of the samples were carried out by using UV-Vis spectroscopy, XRD and FESEM. The results of UV-VIS spectroscopy indicate that palladium
nanoparticles prepared with the ratio of CTAB : PVP = 17 ml : 3 ml, and with a
duration time of 4 hours + 4 hours have the highest absorption intensity. XRD results confirmed
the present of palladium nanoparticles by two peaks at 2θ = 40.122° and 46.664° with orientation
of (111) and (200). Whereas, FESEM images showed that palladium nanoparticles prepared with the ratio of CTAB:PVP = 17 ml : 3 ml, and with a duration time of 2 hours + 2 hours have
uniform sizes of about 13.4- 17.9 nm and have high density of about 0.2325%.
