摘要(Abstract)：

应用水热法,以钼酸铵、硝酸铋为原料,研究水热反应时间对制得的Bi_2MoO_6晶体的光催化效果影响。采用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、比表面积分析仪(BET)、X射线光电子能谱仪(XPS)和紫外-可见漫反射(UV-Vis DRS)对制得的样品进行表征。结果表明:反应时间对Bi_2MoO_6晶体的物相组成、形貌以及光催化性能均有影响。在可见光(λ≥420 nm)照射下,通过光催化降解罗丹明B(Rhodamine B,Rh B)的实验可以探知反应时间对制得的Bi_2MoO_6晶体的光催化活性的影响。当反应时间为16 h时,所制得的样品为纯相Bi_2MoO_6,其光催化效果也最好;在可见光照射下50 min后对初始浓度为5 mg·L-1的罗丹明B溶液的降解率为85%。
