摘要
采用金属铜为“牺牲”阳极 ,首次在无隔膜电解槽中 ,电化学溶解金属铜一步制备了纳米CuO前体Cu(OEt) 2 ,Cu(OBu) 2 ,Cu(acac) 2 ,Cu(OEt) (acac) ,Cu(OBu) (acac) (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铜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 3 0～ 5 0℃ ,采用有机胺溴化物为导电盐 ,电极电位控制在 0 8～ 1 2V之间 ,可以提高电合成效率 .实验同时表明Cu(acac) 2 ,Cu(OEt) (acac) ,Cu(OBu) (acac)
Copper complexes were directly prepared by electrochemical dissolution of copper in a cell without separating the cathode and anode spaces. The products were characterized by FT-IR and Raman spectra. The influence of temperature and conductive additives on product yield was also investigated. The experiments show that controlling temperature under 30～40 ℃ and selecting R 4NBr as conductive additives improved product yield. The data also show that direct electrochemical preparation of copper complexes had high current efficiency and electrolysis yield. These copper complexes have high purity and can be directly used as precursor of nanometer oxides.
