| 摘 要： | 采用一步水热合成法制备不同掺杂量的Sm~(3+)-BiPO_4光催化剂。用XRD,EDS,SEM和DRS手段对光催化剂的特性进行表征。以亚甲基蓝为目标污染物,考察了Sm~(3+)-BiPO_4的光催化活性。结果表明,适量的钐掺杂使BiPO_4光催化活性提高了30%。当钐掺杂量为5%时,紫外光照射90 min,亚甲基蓝的降解率可达86.1%。

| Abstract: | The Sm3+ -BiPO4 photocatalysts with different doping amount are prepared by a facile hydrothermal process . The photocatalysts are characterized by XRD ,EDS ,SEM ,and DRS .The photocatalytic activities are evaluated by the degra-dation of methylene blue .It is found that the photocatalytic activity of BiPO4 increases 30% owning to the adding of Sm . When the doping amount is 5% ,the degradation efficiency of methylene blue in 90 mins can reach 86 .1% under the UV light irradiation . |
