文摘 通过水热法制备了ZnFe_2O_4催化剂,使用扫描透射电镜、能量分散谱仪和X射线衍射仪等表征手段分析其微观形貌、化学组成和晶体类型;研究了其对双酚A (BPA)废水的光催化降解性能,考察H_2O_2投加量、催化剂循环使用次数对催化降解效果的影响。结果表明,所制备的ZnFe_2O_4为木屑状、具有微孔结构的立方尖晶石型材料;单一ZnF_2O_4在紫外光激发下对BPA废水具有光催化降解能力,反应120min,BPA降解率为81.6%;在添加H_2O_2后,系统催化性能得到提升,反应90 min, BPA降解率高达98.5%;优化的H_2O_2投入浓度为1 mmol/L。所制备ZnFe_2O_4有稳定的催化能力,可循环利用。
其他语种文摘 ZnFe_2O_4 fenton-like catalyst was fabricated by hydrothermal method. The morphology, composition and crystal structure of ZnFe_2O_4 were characterized by SEM, EDS and XRD. The photo-catalytic performance of ZnFe_2O_4 was studied. The effects of H_2O_2 dosage and recycle of catalyst on the BPA degradation were investigated. The results showed that ZnFe_2O_4 had the sawdust-like, porous microstructure and cubic structure of spinel-phase. As-prepared ZnFe_2O_4 exhibited remarkable ability to remove BPA under UV irradiation, as 81.6% remove ratio at 120 min. The catalytic performance of the system was enhanced after adding H_2O_2, as 98.5% remove ratio at 90 min. The optimal concentration of H_2O_2 was 1 mmol/L. The prepared ZnFe_2O_4 has stable catalytic capability, which can be recycled.
