摘　　要：以Bi(NO 3) 3?5H 2O和(NH 4) 6Mo 7O 24·4H 2O等为原料,采用混合溶剂热法制备了γ-Bi2MoO 6。采用X-射线粉末衍射(XRD)、红外光谱(IR)和扫描电镜(SEM)等手段对制得的γ-Bi 2MoO6进行了分析表征。所得产物为单相微米球状,光催化实验显示产物具有一定的降解甲基橙性能,循环伏安曲线显示产物能够促进KK 4Fe(CN) 6/ K 3Fe(CN) 6电对之间的电子传递。γ-Bi 2MoO 6was prepared by a mixed solvothermal method, using Bi(NO 3) 3·5H 2O and (NH 4) 6Mo 7O 24·4H 2O as raw materials. X-ray powder diffraction (XRD), infrared spectra (IR), and scanning electron microscopy (SEM) were used to characterize the as-prepared γ-Bi 2MoO 6. The as-prepared products showed a single phase and a microsphere structure. The photodegradation test showed that γ-Bi2MoO6 had performance degradation of methyl orange. The cyclic voltammetry demonstrated that γ-Bi2MoO6 accelerated the rate of electron transfer of K 4Fe(CN) 6/ K 3Fe(CN) 6.
