摘　　要：以醋酸镉和钼酸钠为主要原料,通过自制的滴定-沉淀装置和方法在室温下制备了钼酸镉微/纳晶体。产物经X射线衍射仪(XRD)、扫描电子显微镜(SEM)等表征,结果表明,沉淀陈化环境会影响到钼酸镉晶体产物的尺寸和形貌。光催化降解实验结果表明:钼酸镉晶体在紫外光照下对罗丹明B染料有较好的降解作用,钼酸镉晶体颗粒尺寸越小,降解效果越好。Cd Mo O4 micro/nano crystals were prepared by titration-precipitation method at room temperature with Cd（Ac）2 and Na2MoO4 as raw materials.The as-obtained products were characterized by powder X-ray diffraction（XRD） and scanning electron microscope（SEM）.The characterization results showed that the size and morphology of CdMoO4 were affected by precipitation and aging environment.The results of photocatalytic degradation experiment showed that the CdMoO4 crystal could degrade Rhodamine B under the irradiation of UV light,and the CdMoO4 crystal smaller,the performance better.
