摘要
Cobalt platinum nanorods, hyperbranched nanorods, and nanoparticles were synthesized in 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, [BMIM][Tf2N], ionic liquid though the thermal reduction of platinum acetylacetonate, and cobalt acetylacetonate at 350 °C in the presence of cetyltrimethylammonium bromide (CTAB). It was found that the morphology, composition, and crystal phase of the resultant CoPt alloy nanomaterials could be controlled by changing the concentration and molar ratio of platinum and cobalt reactant precursors.
