| 摘 要： | 以Bi(NO_3)_3·5H_2O和Na_2WO_4·2H_2O为主要原料,采用水热法合成了纯相Bi_2WO_6,并对其进行非金属离子Br-掺杂改性。采用XRD、SEM、TEM、XPS、Raman、PL和DRS研究了Br~-掺杂对Bi_2WO_6的物相结构、形貌和可见光催化性能的影响。结果表明,Br-掺杂可有效提高Bi_2WO_6的可见光催化性能,当掺杂量(物质的量百分数)为8%时,溴掺杂Bi_2WO_6的光催化性能最好,可见光照射40 min后,可降解96.73%的罗丹明-B,与未掺杂Bi_2WO_6相比,其降解率提高了36.32%。

| Abstract: | Br- ions doped Bi2WO6 was prepared using bismuth nitrate Bi(NO3)3·5H2O and sodium tungstate Na2WO4·2H2O as raw materials by hydrothermal synthesis method. The effect of Br- doping on the phase structure, morphology and visible light catalytic properties of Bi2WO6 was investigated using XRD, SEM, TEM, XPS, Raman, PL and DRS. The results indicated that the visible-light-driven photocatalytic performance of Bi2WO6 was greatly enhanced after Br- doping. When Br- was doped with 8% of the amount (percentage of amount of substance), the Bi2WO6 photocatalyst displayed the best photocatalytic performance. It could decompose 96.73% RhB after 40 minutes irradiation, which was 36.32% higher than that of the pristine one. |
