formate complex having long-chainamine ligands within an extremely short time under microwave irradiation. Formate ion coordinated to Ni 2+ ion acted as a reducing agent for Ni 2+ in this reaction and finally decomposed to hydrogen and carbon dioxide. Ligation of the long-chainamine lowered the reaction temperatures by decreasing the energy barrier required for the reduction of the nickel formate
我们通过在微波辐射下在极短的时间内通过分子内还原具有长链胺配体的甲酸盐配合物中的 Ni 2+ 离子,成功制备了面心立方 (fcc) Ni 纳米颗粒。与Ni 2+ 离子配位的甲酸离子在该反应中作为Ni 2+ 的还原剂,最终分解为氢气和二氧化碳。长链胺的连接通过降低还原甲酸镍络合物所需的能量势垒来降低反应温度。使用甲酸镍与几种链长的烷基胺如油胺(=(Z)-9-十八碳烯胺)、肉豆蔻胺(=十四烷基胺)和月桂胺的复合物制备了平均尺寸为 43、71 和 106 nm 的单分散镍纳米粒子(=十二胺),分别。
