中文摘要	in synthesis in a solution phase, adsorbates such as halides can interact selectively with different metal crystal facets and affect the final morphology of nanocrystals. pseudo-halide thiocyanate ions (scn(-)) can also adsorb on the metal surface, but they have never been used for the synthesis of shape-controlled colloidal metal nanocrystals. in this study, we first investigated the effect of scn(-) on the morphology of palladium nanocrystals through a seed-mediated growth method. the presence of 1 mu m scn(-) in the growth solutions could lead to the formation of palladium polyhedra: truncated rhombic dodecahedra enclosed by twelve {110}, eight {111} and six {100} facets. the products were nanocubes enclosed with six {100} facets if cetyltrimethylammonium bromide (ctab) was the only capping agent. meanwhile, the mechanism of the effect of scn(-) on the morphology of pd nanocrystals is discussed.
