摘　　要：采用金属镍为“牺牲”阳极 ,首次在无隔膜电解槽中 ,电化学溶解金属镍一步制备了纳米NiO前驱体Ni(OEt) 2 ,Ni(OBu) 2 ,Ni(OEt) 2 (acac) 2 ,Ni(OBu) 2 (acac) 2 [acac为乙酰丙酮基 ].产物通过红外光谱 (FT IR)、拉曼光谱 (Ramanspectrum)进行表征 .同时讨论了影响电合成镍醇盐及其配合物的关键因素 .实验表明 ,防止阳极钝化 ,温度控制在30～ 40℃ ,采用有机胺溴化物为导电盐 。Nickel complexes were directly prepared by electrochemical dissolution of nickel in non-aqueous media. The products were characterized by FT-IR spectrum and Raman spectrum. The influence of temperature and conductive additives on product yield was also investigated. The experiments at the temperature under 30～40 ℃ with R 4NBr as a conductive additive gave improve yields. The study showed that the direct electrochemical preparation of nickel complexes had high current efficiency and electrolysis yield. These nickel complexes had high purity and could be directly used as precursor of nanometer oxides.
