摘    要:以一种Cu-MOF(HKUST-1)为模板,将其经不同温度的热处理制备铜氧化物,研究了热处理温度对产物组成及形貌的影响,并通过产物在一系列条件下活化过一硫酸氢钾(PMS)降解水体中罗丹明B(Rh B)的实验探究了其催化性能.XRD、SEM、XPS等表征结果表明,随着热处理温度的升高,产物由Cu2O/CuO混合物逐渐转化为纯相CuO,且模板HKUST-1的原有正八面体结构坍塌加剧.Rh B降解实验的结果显示,催化剂对PMS的活化性能随热处理温度的升高而加强.在中性pH条件下,当PMS投加量为1.00 mmol·L~(-1),CuO-650用量为0.20 g·L~(-1)时,反应时间进行90 min基本可实现Rh B(浓度为0.10mmol·L~(-1))的完全降解.此外,CuO-650还具有pH适用范围较广,铜离子溶出量较低(pH=3条件下为1.309 mg·L~(-1),pH=7条件下为0.987 mg·L~(-1)),循环稳定性较佳的特点,进一步证明CuO-650是一种很有潜力的PMS催化剂.

Abstract:Using Cu-MOF (HKUST-1) as a template, copper oxide was prepared by heat treatment under different temperatures in this study. The effect of treatment temperature on the composition and morphology of the products were studied. The catalytic abilities of the copper oxide products were tested through a series of experiments of activating peroxymonosulfate (PMS) to degrade RhB under different conditions. The results of XRD, SEM, and XPS show that the product is gradually transformed from a Cu2O/CuO mixture into pure CuO with the increase of heat treatment temperature. The original octahedron structure of HKUST-1 was collapsed. Under neutral pH conditions, when the dosage of PMS and CuO-650 was 1.00 mmol·L-1 and 0.20 g·L-1, respectively, the total degradation of RhB (concentration of 0.10 mmol·L-1) could be completed within 90 min. In addition, CuO-650 also has many advantages, such as it can be applied within a wide range of pH values. In addition, the copper ion dissolution rate was low (1.309 mg·L-1 at pH=3 and 0.987 mg·L-1 at pH=7), and it has great recyclability and stability. These characteristics further proved that CuO-650 can be used as a promising catalyst for PMS activation.
