摘　　要：采用均相法合成纳米硫化亚铜(Cu_2S),通过XRD、SEM对Cu_2S进行了表征分析。结果显示,合成的Cu_2S晶粒结晶度好,粒径小且均一。采用单因素结合响应面法,以产率为评价指标,探讨了铜盐比、反应温度及反应时间对均相合成硫化亚铜产率的影响。采用二次回归方程模型,预测均相合成硫化亚铜产率最高(99.862%)时,各因子的最优值分别为:铜盐比0.46,反应温度92.60℃,反应时间为6h。验证实验误差小于3%,表明该模型与实际情况拟合良好。Nano cuprous sulfide（Cu_2S） was synthesized by homogeneous precipitation method, and the nano Cu_2 S was characterized by X-ray diffraction（XRD）, Scanning Electron Microscope（SEM）. The results showed that the synthesis of Cu_2 S grain had good crystallinity, small grain size and uniform. Process was optimized by single factor combined with response surface method, the copper salt ratio, reaction temperature and reaction time impacted on the homogeneous synthesis of cuprous sulfide production rate was discussed. According to the quadratic regression equation model predicts, the yield was the highest（99.862%） when each factor to the optimal value were： copper salt ratio 0.46, the reaction temperature 92.60 ℃ and react 6h. The verify experiment error was less than 3%, which indicated that the fitting model was fitted for the actual experiments well.
