摘　　要：以CuSO4·5H2O为原料,首先制备出碱式碳酸铜前驱体.在350℃焙烧1h后,制备出 氧化铜纳米粒子,经XRD和TEM检测,粒径为30nm.在十二烷基苯磺酸钠水溶液中加入氧 化铜纳米粉,用稀HNO3,调节介质pH=3.0,得到均匀分散的氧化铜纳米粉水溶胶.Nanoscale CuO powders were prepared by roasting a basic coppper carbonate precursor at 350C for 1 h. The obtained sample's microstructure was determined by XRD and TEM analysis. The results show that the diameter of the nanocrystalline is 30 nm. CuO sol were prepared with dodecylbenzene sulfonate solusion and at pH=3.0 adjusted by HNO3.
