摘要/Abstract

摘要： 以Bi（NO₃）₃·5H₂O和Na₂WO₄·2H₂O为原料，NaOH为pH调节剂，采用一步水热法在160℃合成出了Bi₂WO₆纳米材料，对所制备Bi₂WO₆材料进行了表征。并考察了前驱物pH对Bi₂WO₆材料光催化性能的影响。结果表明，pH对制得Bi₂WO₆样品的晶相结构、光学性质、比表面积以及催化性能都有较大影响。pH=9时，Bi₂WO₆光催化效果最佳，在氙灯照射120 min后，MB的降解率达到80.9%，照射180 min后，RhB的降解率达到84.7%。

关键词: Bi₂WO₆, 水热法, 光催化性能

Abstract: Bi₂WO₆ nano-materials have been synthesized by one step hydrothermal method at 160℃,using Bi(NO₃)₃·5H₂O and Na₂WO₄·2H₂O as raw materials,NaOH as pH regulator,and the prepared Bi₂WO₆ materials characterized. The influences of predecessor pH on the photo-catalytic capabilities of Bi₂WO₆ nano-materials have been investigated. The results indicate that pH has comparatively great influences on all the phase structure,optical property,specific surface area and photocatalytic capability of the prepared Bi₂WO₆ samples. When pH=9,the Bi₂WO₆ photo-catalytic effect is the best. After being irradiated for 120 min under xenon lamp,the MB degradation rate reaches 80.9%,and after being irradiated for 180 min,RhB degradation rate reaches 84.7%.

Key words: Bi₂WO₆, hydrothermal method, photo-catalytic capability
