| 摘 要： | 采用银氨辅助法合成了Ag_3PO_4,超声波分散法制备Ag_3PO_4/ZnO复合物,利用X-射线衍射(XRD)和扫描电镜(SEM)对催化剂进行了表征.在超声照射下,讨论了煅烧温度、煅烧时间、照射时间和染料浓度等对甲基橙降解率的影响.结果表明:Ag_3PO_4/ZnO在煅烧温度为450°C,煅烧时间为60min,超声照射180min时,甲基橙降解率可达85.36%,高于纯ZnO时的降解率.

| Abstract: | Ag3PO4 was synthesized by silver ammonia auxiliary method, and Ag3PO4/ZnO was mixed by ultrasonic dispersion, Ag3PO4 and Ag3PO4/ZnO were characterized by XRD and SEM. The influence of preparation conditions, such as irradiation time, heat-treated temperature, heat-treated time and the concentration of methyl orange on the degradation efficiency were investigated under ultrasound irradiation. The results revealed that the degradation ratio of methyl orange dye in the presence of Ag3PO4/ZnO reached 85.36 % at the 450 °C, 60 min and 180 min, which was obviously higher than the corresponding degradation ratio in the presence of un-doped nanometer ZnO. |
