  • 摘要: 以醋酸锌(Zn(CH3COO)2) 和六水合硝酸铕(Eu(NO3)3·6H2O)为主要原料,氢氧化钠(NaOH)为沉淀剂,聚乙二醇(PEG2000)为矿化剂,柠檬酸为pH调节剂,采用水热法制备Eu掺杂ZnO复合纳米棒光催化材料粉体。用制备的粉体对制药废水进行光催化降解实验,并研究了反应温度、反应时间、光照条件和掺杂比对其光催化氧化效果的影响。用XRD、TEM和EDS等测试手段对粉体进行了表征。研究结果表明,水热反应温度为160℃,时间为6 h,制备的3%Eu掺杂ZnO复合纳米棒光催化材料的光催化效果较好,在365 nm的紫外灯照射下150 min后,制药废水的脱色率达38.8%,COD的降解率达57.5%。
    Abstract: In this study,Europium-doped zinc oxide (Eu·ZnO) nano-particles were prepared using hydrothermal method by taking Zn(CH3COO)2 and Eu(NO3)3·6H20 as main ingredients,NaOH as precipitant,PEG2000 as mineralizer,citric acid as pH modulator.The prepared powder was used for photocatalytic degradation,in which the influence ofreaction temperature,reaction time,illumination conditions as well as the doping ratio on the effect of photocatalytic oxidation were throughly investigated.Analytical methods,such as XRD,SEM and EDS were utilized in this study for characterization of the prepared powder.Our results showed that Europium-doped zinc oxide with a 3% doping ratio reached optimal photocatalytic oxidation effect when the hydrothermal temperature was 160℃ and hydrothermal time was 6 hours.By utilizing the prepared powder under optimal conditions,the decolorization rate of pharmaceutical wastewater reached 38.8% after treatment of 365 nm UV irraditation for 150 min,and the degradation rate of COD reached 57.5%.
