在十六烷基三甲基溴化铵（CTAB）的存在下，通过在350 °C下热还原乙酰丙酮铂和乙酰丙酮钴，在1-丁基-3-甲基咪唑双（三氟甲基磺酰基）酰亚胺[BMIM][Tf 2N]离子液体中合成钴铂纳米棒、超支化纳米棒和纳米颗粒。结果表明，通过改变反应物前驱体中铂和钴的浓度和摩尔比，可以控制CoPt合金纳米材料的形貌、组成和晶相。
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.
