Optimation growth of platinum and palladium nanoparticles on stainless steel 316L and activated carbon pellet substrates
In this study, an optimation growth of platinum (PtNs) and palladium (PdNs) nanoparticles has successfully grown on stainless steel 316L and activated carbon pellet as substrates. PtNs and PdNs were grown on the substrates by wet chemical method. The effect of concentration of ascorbic acid and multi-growth step had shown the significantly in density and particle size distribution on the both substrates. The morphology and the structure of PtNs and PdNs were characterized by a field-emission scanning electron microscope (FESEM), X-ray diffraction (XRD), respectively. Homogenous particles size and high density of PtNs and PdNs on the substrates were also successfully grown with current method.
