络合沉淀法制备高纯白色二氧化铈及其光催化的研究
Preparation of High-Purityand White CeO2 by Complex-Precipitation Method and Its Photocatalytic Activit
摘要
Abstract
The cerium oxide was prepared by complex-precipitation method using ethylene diamine tetraacetic acid disodium salt as precipitator and complexing agent . The methylene blue was photocatalyzed to degrate by CeO2 as catalyst . The experiment researched the influence of the amount of complexing agent ,reaction time and temperature on the cerium oxide .It was characterized by XRD ,SEM ,UV ,IR .The results show that the optimal condition of preparing CeO2 is the mole ratio of ceric sulfate and complexing agent is 1∶3 ,reaction time is 1 h ,temperature is 60 ℃ .The high purity and crystalline cerium oxide was prepared by complex-precipitation method .The experiment researched photocatalytic activity of CeO2 and discussed the effect of catalyst dosage ,hydrogen peroxide ,pH ,time on degrading methylene blue .The results show that the optimal condition of photocatalysis is catalyst dosage is 20 mg ,the amount of hydrogen peroxide is 6 mL ,pH was 6 ,the photocatalytic time is 120 min in the 100 mL solution of methylene blue .关键词
