Abstract
We have successfully implemented a facile, one-pot solventless synthesis procedure starting from acetylacetonate salts and CaH(2) to obtain carbon-coated ferromagnetic metallic Ni and Fe nanoparticles at low temperature. The use of CaH(2) as a reductant drastically reduces reaction temperature down to 140 °C.
摘要
我们成功地开发了一种简便的一锅无溶剂合成方法，该方法从乙酰丙酮盐和氢化钙（CaH(2)）出发，在低温下获得了包覆碳的铁磁性金属 Ni 和 Fe 纳米粒子。使用 CaH(2) 作为还原剂可将反应温度急剧降低至 140°C。
