硝酸根体系下合成氧化亚铜立方体

Growth of Cuprous Oxide under the Liquid of Sodium Nitrate

摘要: 在硝酸根体系中制得纯净的Cu₂O粉体,考察了温度、时间、硝酸根含量、填充度等不同因素对反应的影响。结果表明,反应温度为373K,反应时间为2h,1.00 mol/L NaNO₃加入量为反应溶液的4.0倍,填充度为玻璃水热反应釜容积的0.8时是制备Cu₂O的最佳条件,能够得到粒径为8μm的纯净的Cu₂O立方状粉体。

Abstract: Main factors which influence the preparation,reaction of Cu₂O powder such as the reaction temperature,reaction time,and dosage of sodium nitrate solution are investigated,and an optimal experiment of the hydrothermal synthesis was conducted.The results indicate that reaction at 373K for 2 hours with a dosage of sodium nitrate solution four times as much as that of the reactive solution is optimized with which 8 μm cubic particles could be yielded.
