| 摘 要： | 以十二烷基硫酸钠为形貌控制剂,醋酸锌和氢氧化钠为原料水热制备氧化锌。以甲基橙作为光催化降解的对象,实验结果表明,溶液初始浓度为0.5 mol.L-1、反应时间为24 h、反应温度120℃,氧化锌的光催化活性最佳,太阳光照2 h后,甲基橙的降解率为76.5%。XRD测试表明,ZnO为六方红锌矿相,SEM观测显示,ZnO晶粒主要呈规整八面体。

Preparation and photocatalytical performance of ZnO with special morphology by hydrothermal method |

| Abstract: | ZnO particles were synthesized by the hydrothermal method using sodium dodecyl sulfate as morphology control agent,and Zinc acetate dihydrate and sodium hydroxide as raw materials.With degradation of methyl orange as a experimental object,the results showed that,when initial concentration was 0.5 mol.L-1,reaction time was 24 hours,and reaction temperature was 120 Celsius,ZnO have the best photocatalytic activity,correspondingly the degradation rate of methyl orange reached 67.4% after UV irradiation for two hours.XRD characterization indicated that mineral name of ZnOis red zinc hexagonal phase.SEM observations show ZnO grains were mainly regular octahedron. |
