摘　　要：通过改变表面活性剂的种类利用水热法成功制备不同形貌的β-Zn MoO4材料。采用X射线衍射(XRD)、扫描电子显微镜(SEM)和紫外-分光光度计(UV-Vis)对样品的晶相、形貌和光吸收进行测试。通过样品对亚甲蓝废水的吸附及光降解效果来考察其性能。重点研究不同表面活性剂对β-Zn MoO4材料的相结构、形貌、禁带宽度及光催化性能的影响。结果表明,表面活性剂可以降低材料尺寸,获得具有较好亚甲蓝吸附性能的棒状或花状β-ZnMoO4。采用十六烷基三甲基溴化铵(CTAB)能获得较小尺寸和增强光吸收能力的β-Zn MoO4,其对亚甲基蓝的光催化降解率可达94. 2%。β-ZnMoO 4 materials with different morphologies were prepared by hydrothermal method via changing the kinds of surfactants.The phase,morphology and light absorption of these materials were characterized by XRD,SEM and UV-Vis.The effect of adsorption and photodegradation of methylene blue of the samples were also investigated.The influences of surfactants on theβ-ZnMoO 4 materials phase structure,morphology,optical energy gap and photocatalytic performance were investigated.The results show that surfactants could make the materials sizes reduce,and could obtain rodlike or flower-likeβ-ZnMoO 4,which exhibited better adsorption properties for methylene blue.Using cetyltrimethyl ammonium bromide(CTAB)can promote the smaller size and enhanced light absorption capacity ofβ-ZnMoO 4,and the photocatalytic performance rate of methylene blue reached 94.2%.
