| 摘 要： | 以Nd（NO3）3·6H2O和Na2WO4·2H2O为原料，采用微波水热法在160℃～220℃反应90min成功合成了NdWO4（OH）粉体，利用X射线衍射（XRD）和扫描电镜（SEM）对所合成的NdWO4（OH）粉体进行了表征，讨论了合成温度对NdWO4（OH）粉体晶体结构和微观形貌的影响，并对所合成粉体的光催化性能进行了研究．结果表明：合成温度对NdWO4（OH）粉体的晶体结构和微观形貌均有明显影响；在紫外光下照射120min，200℃合成的NdWO4（OH）粉体对RhB溶液的降解率达93．0％．

| Abstract: | NdWO4 （OH） powders were successfully synthesized using Nd （NO3）3· 6 H2 O and Na2WO4 · 2H2O as raw materials via a Microwave-Hydrothermal method at 160℃-220 ℃ for 90 min, the attained NdWO4 （OH） powders were characterized by X ray diffraction （XRD）, field emission scanning electron microscope（FESEM）, the effect of synthesis tern perature on the phase and morphology of NdWO4 （OH） powders was discussed, and the photocatalytic properties of the attained powders were also investigated. The results indicate that the synthesis temperature has an obvious effect on the phase and morphology of NdWO4 （OH） powders. The degradation rate of RhB solution reaches to 93. 0% under ultraviolet light irradiation for 120 min with NdWO4 （OH） powders as catalyzer prepared at 200 ℃. |
