中文摘要:
      采用水热法原位合成了Ru掺杂BiOBr空心微球(Ru/BiOBr)复合光催化剂,并对其进行了XRD、SEM、TEM、EDS、DRS、EIS等表征.结果表明,所合成的BiOBr材料是由许多小厚度的交错纳米片自组装而成的,同时Ru纳米颗粒成功负载到BiOBr表面,该复合材料对还原CO2和降解有机模拟污染物(罗丹明B,RhB)具有良好的光催化性能.当Ru的掺杂量为0.4%时复合材料的光催化活性最佳,4 h后甲醇产量可达1103 μmol/gcat,并且60 min内对RhB的降解率达到98%.除此之外,还讨论了复合材料的光催化机理和稳定性.
英文摘要:
      Ru doped hollow BiOBr microsphere (Ru/BiOBr)was prepared as a photocatalyst by an in situ hydrothermal method. The prepared materials were characterized by XRD, SEM, TEM, EDS, DRS and EIS technologies. The results showed that the composite was assembled by numerous interleaving nanosheet petals with small thickness, and the Ru nanoparticles were successfully loaded onto the surface of BiOBr. As-prepared composite had good photocatalytic performance for reduction of CO2 and degradation of organic simulated pollutants (rhodamine B, RhB). As the result, 0.4% Ru/BiOBr exhibited exellent photocatalytic efficiency, where the yield of methanol reached up to 1103 μmol/gcat during 4 h and the degradation rate of RhB reached up to 98% within 60 min. Meanwhile, the possible mechanism and stability of excellent photocatalytic performance of Ru/BiOBr were also investigated.
